Sam Lewis was a big-time player that head coach Ryan Odom brought back to the team last season. He is one of three starters who make their return to the Cavaliers this season. It was a big-time return for Coach Odom and gives him some continuity to the starting lineup. He now pairs dynamite point guard Chance Mallory with Lewis to make a formidable backcourt. We saw the pair close out quite a few games together last season. CBS Sports writer Isaac Trotter highlighted Lewis as a second-year transfer poised to make a jump. Here is what he said.  “Lewis assimilated into the ACC nicely after transferring in from Toledo. The sleek, 6-foot-6, 210-pound wing started 35 games, averaged over 10 points and drained 40% of his 3-pointers in 25.4 minutes for a deep Virginia club that earned a No. 3 seed in the NCAA Tournament. Lewis would've been a top-30 player in the transfer portal if he had entered. Instead, Virginia gets him back for a second season in Hooville.”  What does he need to improve?…
