I like how you set up your post, Johnny 4 Life, and I'm gonna disagree on a few points. I bring up free throws a lot because this team is (I guess) built to slash, not to hit deep jump shots. Point by point:
PG: I think the team won't miss Geno's slow set up, his turnovers, or his shot, but they will miss Geno's ability to play tough defense on the slower point guards, generate steals, and get to the free throw line. Boothe, being a shooter I wouldn't trust, has to get to the line; he has to play his D without fouling (I agree with you on that) and it'd be nice if knocked the ball loose from some players. It's disruptive and one of the best traits Geno had. Edmondson, by the way, might be back up material, and he might be last year's Paris Horne, a no-pass, streak-shooting, questionable-dribbling guard, but this one would have the ball in his hands. We don't know.
SG: Kennedy is going to start. I missed the part where Horne shot more or well at the end of the season. He had a good game against Marquette in the last 5 and that's it. If he improves his handle on his drives (and gets to the line), he might have something going there.
Meanwhile, Kennedy looked lost when he played next to Mase; he didn't look for his shot (as he did in the NEC part of the season) until the end of the season. I think he has a chance to really break out if he figures out how to get his drives to the basket in (and finish when he gets there). And the team needs a second dribbler. He needs to be it, since he likes to push the ball aggressively.
SF: Mase will be much the same, hopefully, as the end of the season. I'm not holding my breath, but when healthy, he had some very good games, showed some quickness. Hopefully when he's on the way to a 3-14 clunker he'll look to drive the ball and pass to Burrell, which he did effectively at times.
PF: Agreed on Burrell. Especially about the getting stronger. If he gets the ball in better positions, and gets easier shots in some way (43% from an interior scorer isn't good), he'll be nice. He's got a nice midrange stroke, too, opening up his game.
C: Coker's got to be better with his feet and positioning. I think Evans will get a lot of time unless Coker comes back as a non-fouling beast. Coker's per-40 minute numbers would have him fouling out of every single game; if Evans learns a bit more about offensive and defensive basketball, he'll be an okay bench player. Both guys need to hit a free throw.
Then of course there is Thomas. At the very least, he'll be an upgrade - the limited minutes he played on that knee weren't terrible, and he knows the game.
Jasiulionis will swing his towel more energetically than before! I hope he is studying game film and becomes a non-playing assistant coach. Or at least when he plays, learns to just use his height.
Wait is tall and hopefully, strong enough to spell some of the interior guys. Maybe he can hit a shot. Who knows. And Roberts, I hope he's a good outside shooter. The squad could use it. But I think it'll come back to the 9 returning players (outside of Jasiulionis).
