I agree with the OPs sentiment.
But those who are expecting him to be Shaq [or even Rak, sticking to an example closer to the program] are setting themselves up for disappointment.
But 8 / 10, finishing the ones he's supposed to, not being a 45% liability at the FT line, and a guy who can consistently score in double figures any given game? Absolutely.
It's important to keep in mind that the kid was basically unproven at the beginning of the season. He'd played, but only intermittently. Nobody knew whether he could stay healthy, play pain-free, etc. He needed to get some game PT under his belt, to figure things out. None of those issues will be factors next year. His senior season, he'll be an experienced guy who's had / learned from / expanded his game as a function of going through ups and downs.
i'd be really surprised if we don't see more emphasis on inside scoring next year, sans Eli -- to capitalize on Sidibe / Guerrier. And I wouldn't be surprised to see him be a double-double guy.
Now - the question is, will he become a better defensive presence? Because if so, he could have a VERY effective senior campaign if the last four games are something he builds upon.
A big key offensively at least -- and probably a pretty obvious one -- is limiting fouls. This is completely arbitrary in terms of statistical significance, but relevent in the sense that when Sidibe has been able to stay on the floor for longer stretches he's been pretty effective (offensively at least).
Consider the games where Sidibe has played at least 27 minutes (that's the arbitrary part). His numbers in those 13 games (hard to believe he's only gotten to 27 minutes 13 times):
8.8 ppg, 8.3 rpg, 1.7 steals, 1.84 blocks
In ACC games where he has logged at least 27 minutes he's been even better across the board (statistically at least):
9.6 ppg, 9 rpg, 2.25 steals, 2 blocks
Our record in the 13 games was 9-4 (losses to a top 25 iowa team where we did get crushed defensively inside, top 10 FSU on the road in a game that went to the wire, and the brutal G'town/UNC losses). In the 8 conference games we were 6-2 with FSU/UNC as losses.
So what does it all mean? I don't know. Do we maybe beat Penn State or Clemson with Sidibe staying on the floor? Maybe. But ultimately the one takeaway is that when he can avoid major foul trouble, he's not a bad guy in the middle of the floor. Maybe not great, but not bad. Need to get him to at least be available for closer to 27 mpg next year instead of the 23.5 he's currently logging (even after four straight of 27+).
It would also help Edwards, by the way, b/c we'd be asking for 10-ish minutes out of him instead of 15-20.
