Shump is our only player under 27 years of age. So he's litterally the only player of ours who's supposed to drastically improve in the next 4 years. We most definitely can't/shouldn't trade him for a JJ Redick rental.
I don't know about Jordan Lite, but I think Shumps potential and game (offense+defense) are most similar to Gary Payton. They're almost the same height too at 6'4"/6'5". And both are defensive players first and foremost. One thing Payton shares with Jordan is being the only guard to ever win the Defensive Player of the Year Award. I can see Shump evolving into that 3rd guard in NBA history to do that.
Look at Payton's first 3 seasons:
1st season, age 22:
27,4 MPG, 7 PPG, 45%FG, .077 3ptFG, 6,4 assists, 3 rebs, 2 stls
2nd season, age 23:
31,5 MPG, 9,4 PPG, 45% FG, .130 3ptFG, 6,2 assists, 3.6 rebs, 1.8 stls
3rd season, age 24:
31.1 MPG, 13,5PPG, 49% FG, .206 3ptFG, 4,9 assists, 3.4 rebs, 2.2 stls
Iman's first season, age 21:
28,9 MPG, 9,5 PPG, .40%FG, 30% 3ptFG, 2,8 assists, 3,2 rebs, 1,8 stls
If Shump was given the keys in the same fashion Payton was, his stats IMO would come very close to Payton's. Also, Shump is only 22 years old.. Still plenty of time for him to reach greater levels of play.
