There have been studies that have shown this, or you can just take the Gregg Popovich eye test, but we know this:
Rested players perform better and are less likely to be injured.
Which is why the trend toward resting players in the NBA is not going away. Enter Cavaliers coach Tyronn Lue, via Cleveland play-by-play man Fred McLeod.
LeBron James may not like it, but this is the right move by Lue, both in terms of trying to repeat and for future years. The Cavaliers are going to need a healthy LeBron, Kyrie Irving, and Kevin Love if they are going to pass the test the Warriors present again.
The league schedulers have done an impressive job of reducing the four-games-in-five-nights on the road and back-to-backs. However, as long as the NBA plays 82 games, fatigue and rest will be issues — and we know the owners and players are not giving up the revenue to go to a more reasonable 60-game schedule. Which means what you get now is the new reality.
