Video Breakdown: What is Lock and Trail defense?

Leave a comment

Last time on the glossary we covered an offensive move named after Allen Iverson, but today we’re going to talk about a defensive technique you may have heard of called “Lock and Trail”.

The lock and trail — sometimes called “lock and ride” or “lock and go” — is a defensive method typically used for guarding a jump shooter coming off a screen, but it can also be utilized on dribble handoffs and elsewhere on the floor.

The basic idea is for defenders to come over the top and pressure guys at the arc. That happens when a down screen is set on a shooter, usually below the free-throw line, and the defender “locks” onto his man and “trails” him to the 3-point line, even if he cedes what appears to be an easier route to the basket.

But it’s not meant to be so easy. This is a help defense situation, where the trailing defender is trying to prevent the jumper and the help defenders are preventing the drive.

The technique is built to pressure a shooter off of his spot and back toward defenders until a recovery or full switch can be made, and a good result for NBA coaches utilizing the lock and trail would be a mid-range jumper with the 3-point line and the painted area locked up.

Let’s diagram what that looks like by watching the full video breakdown above, or the write-up below.

Drawing it up

Let’s say you’ve got the start of a set with two posts and two wings down near the block. Defenders here are in white, and the red offense is trying to get the ball to the guard with the yellow star.

In order to get the guard free, the center is going to set a down pick on his defender. The star is going to pop to the arc and curl around to received the pass from the point guard.

Lock and trail means fighting into the direction of the screen, staying on a defender’s shoulder, and following him around to the arc.

Once the offensive player gets to this point, he has to make a choice to dribble toward the basket or pass, where help defenders from the post and the point can dig down and help slow his progress until the trailing defender can catch up.

That’s the basic concept, now let’s check it out on tape.

You can see the lock and trail in action here by the Mavericks against Golden State. Klay Thompson is at the right elbow looking to come of a screen from Draymond Green.

The defender goes up and over to prevent him from getting the shot at the top of the arc, then the help defender comes off of Green to stop the drive before they eventually make a full switch.

Even when players are behind on a play, it can be an effective tool to run guys off the line, especially when it’s mixed with a soft ICE coverage. Rodney Hood is pretty far behind Devin Booker when this play starts, but look at how razor thin he’s cutting this angle off the screen to pressure Booker at the arc.

That’s mixed with an open invitation thanks to this pick-and-roll coverage by Derrick Favors, and Booker takes the bait as he moves toward a midrange shot.

Finally we have the Raptors trying to get DeMar DeRozan off a stagger screen coming to the near side of the floor. Andre Iguodala is down low with him, and doesn’t go over the top, instead locking and trailing to prevent a corner three.

As Iguodala trails, JaVale McGee comes off his man to stunt on DeRozan long enough for Iggy to recover.

That’s the basics of the lock and trail. It’s an alternative to switching screens or cutting underneath them, and now if you hear someone using that terminology, you’ll know that it’s a way for teams to run 3-point shooters off the arc and into the teeth of the defense by coming over the top of screens.

Edmond Sumner declares for NBA draft despite torn ACL

Edmond Sumner has grown about five inches since high school.

That has helped turn the 6-foot-5 Xavier point guard into an intriguing NBA prospect — but also seemingly contributed to physical complications. Sumner missed nearly all of his freshman year with knee tendinitis. Then, after a promising second season and start to his third, he tore his ACL in January.

Still, he’s entering the NBA draft.

Sumner:

Rick Broering of Musketeer Report:

Like with Duke’s Harry Giles, medical testing will be huge with Sumner. But at least Giles ended the season on the court. Sumner might not be healthy at all during the pre-draft process.

Sumner looked like a borderline first-round pick before the injury. This probably pushes him into the second round.

His long strides provide impressive speed and quickness, and he’s still shifty. Add quality court vision, and his ability to drive by defenders is even more valuable.

A 6-foot-8 wingspan and good lateral mobility also help make him a quality defender.

But it’s also concerning that so much of his positives could be undermined by his knee issues, especially considering his unreliable jumper. If Sumner can’t move like he did before getting hurt, I don’t see how he sticks in the NBA.

If Sumner’s knees check out, it’s worth rolling the dice on him and hoping his jumper develops. He might even be OK without shooting range, though that’d lower his ceiling considerably.

Again, though, the first thing is examining his knees.

PBT Extra: Can Boston hang on to the No. 1 seed in East?

In an unexpected twist as the season winds down, the Cavaliers have stumbled — 8-11 since the All-Star break — while the Celtics have just kept on winning. Suddenly the Boston Celtics are on top of the East with the best record.

Can they stay on top through the rest of the season?

Does it matter to the Cavaliers?

I cover all this ground in the latest PBT Extra.

Draymond Green on Raiders move to Las Vegas: I won’t attend another game

The Raiders are moving from Oakland to Las Vegas, and Draymond Green — whose Warriors also play in Oakland is not pleased.

Green, via Monte Poole of CSN Bay Area:

I wouldn’t attend a game. I won’t attend a game.

“And I’m not a diehard Raiders fan, but I support the city of Oakland. It ain’t for me and I feel like all fans should feel that way. You just don’t do that. Come on man, that’s ridiculous.”

“If I were the fans, I wouldn’t attend a game for the next two years. But that’s just me. That’s ridiculous. No way I’d pay my money to attend a game.”

 

Um, does Green realize the Warriors are also moving from Oakland (to a new arena in San Francisco)?

Green:

“It’s one thing if you’re moving them from Oakland to Fremont or something,” Green said of the Raiders. “To Las Vegas?

OK, that’s Fair. I am just being pedantic. I don’t actually see moving across the bay as similar to the Raiders moving hundreds of miles away.

Green:

“That’s like moving the Dallas Cowboys or moving the Packers,” he said. “Moving the Raiders? You can move a lot of teams. Ain’t many fan bases like the Raiders fan base. That’s like moving the Boston Celtics from Boston or the Lakers from LA.

“You just don’t move certain franchises with the fan base they have.”

But seriously this time: Someone tell Green that the Raiders have already moved from Oakland to Los Angeles and back to Oakland — hundreds of miles each way and a ridiculous drive in traffic.

I get that Green — who grew up in Detroit Lions territory, roots for the Pittsburgh Steelers and is pictured above in a San Francisco 49ers jersey — just wants to connect with Oakland fans, but this argument is just intellectually dishonest.

Lonzo Ball: I’m better than Markelle Fultz

Who should go No. 1 in the 2017 NBA draft?

A pair of Pac-12 freshmen point guards, Washington’s Markelle Fultz and UCLA’s Lonzo Ball, lead the discussion.

Fultz looks like the leading contender, but Ball doesn’t buy into the conventional wisdom.

Ball, via ESPN:

“Markelle’s a great player, but I feel I’m better than him,” said Ball, who led the Bruins to a pair of blowout victories over Fultz’s Huskies this season.

“I think I can lead a team better than him,” Ball added. “Obviously he’s a great scorer — he’s a great player, so I’m not taking that away from him.”

This will get spun into a discussion of Lonzo’s father, LaVar Ball. But, without digging deeply, D'Angelo Russell, Shabazz Muhammad and Enes Kanter each claimed to be the best player in their respective drafts. Look further, and there are many more examples.

Reaching Lonzo Ball’s level usually comes with supreme confidence. This is normal — not a cause for concern about the influence of his boastful dad.

And for what’s it’s worth, I’d favor Ball over Fultz right now, though there’s still more information to gather in the draft process.
