Seemingly in line to replace him: Jeff Teague.
Marc Stein of ESPN:
That would make Teague costlier than Rubio, who’s due $29.2 million over the next two years. But the Timberwolves got a first-round pick in the trade with Utah, and Teague – a superior outside shooter – fits better with Jimmy Butler and Andrew Wiggins on the perimeter.
Minnesota could still have about $12 million in cap space, which could go toward a stretch four and just generally rounding out the bench.
