LSF,
Not saying there's no eceptions to the rule, but players are who they are by their sophmore years. That includes MV's list: Jaason Smith, TJ Thompson, Carl Elliott, Rob Diggs, Noel Wilmore. I'll throw in Hall, Omar, Pops, Mike King, Chris Monroe, Yegor, Koul, and most other Colonials.
Players can get more consistent or take on a larger role (Elliott scoring a couple more points with the added minutes but at a lower FG% because the needed his points as a senior) but the main reason for increased stats is clearly additonal playing time. Even Noel: 3 pts, .7 rep, .3 ast in 9 min/game as a sophmore to 7 pts, 1.4 reb, .5 asts as a senior in 18 mins/game. He shot better because he got more consistent playing time. J Smith was misused as a prerimiter player early but found a role down low as a senior and A Hart never really got off the bench until his senior season. Damian Hollis shot the ball better his junior year after struggling his sophmore year with most of his other production numbers staying similar.
For all the other players their production/minutes played as a sophmore generally holds. That would not trend well for Joe Katuka but sometimes athletic but raw big men buck the trend. Joseph averaged about 5pts and 3.5 rebs in 14 min/game in the 2nd half of last year. Maybe he gets 8pts, 5 boards/game in 20-24 mins/game net season but that's about it.
And for those who think that Hollis will be at the SF spot mostly or that Katuka and Edwards will ride the bench: COUNT TO 80. Show me 80 minutes of PF C time without Hollis at the 4 and Katuka at the 5. It can not be done. Katuka's career high in a single game is 23. Anytime over 20 last year he was either in foul trouble or winded (or both). Hope for 20 to 24 from JK. Warren might be a nice freshman but will also probably battle conditoning and foul problems if pushed over 20-25/game.
Combine them for around 45 minutes/game, add 10 for Edwards and you still need around 25 minutes at the 4 from Hollis. That's really just for defense anyways since Hobbs has consistently employed a half-court offense with 1 big man down low. The 4 (Hollis, Hall, Omar, Regis, etc) has mostly played on the perimeter, spoted up at the top of the FT line or romed the baseline for cuts. Hollis will be fine in that role as long as Katuka and Warren can fill the 5 spot.
