I'll try and give my honest assement of each player:
Kevin Pangos - Elite PG... not amazing defensively, but does the job. Cannot be left open, his open threes are automatic... has a nice floater too.
Gary Bell Jr. - a bit small as a combo guard. Can be outright deadly from deep and likely best defender on the team.
Byron Wesley - Transfer from USC where he was leading scorer. Not an outside shooter, has a good midrange shot and drives well.
Kyle Wiltjer - Transfer from Kentucky, has a NC ring, was SEC sixth man for UK... sharpshooter like no other... made 70 out of 75 threes in 5 minutes. Deadly midrange as well and developed a solid inside game during the year off.
Karnowski - A major load down low. Can block and posts very well. Has something that resembles a midrange jumper (if you call 8 feet or less midrange), has a sweet hook and holds the ball high
Dranginis - Solid defender at the 3. Can shoot outside as good as the others. Penetrates but not near at the level of Wesley
Nunez - Playing out of position at the 4, but can shoot outside and work the lane
Sabonis - While not his dad, he is a rebounding machine and plays a solid post game.
With Perkins out... that is likely the rotation.
