Ultimately, its up to the player. He's always had the athletic tools. He began showing more offensive skill last season. But he wasn't focused. This year he is.
Lack of killer instinct? Not enough want-to? Island mentality / too laid back? Whatever you want to label it, Rak was too comfortable drifting around the court without doing too much for three years. I don't disagree that we traditionally suck feeding the post and generally don't emphasize the pivot most seasons [this year being a notable exception]. Even so, his contributions were lacking for somebody with his physical gifts because he spent the better part of three seasons going through the motions.
Rak's issues have been more about Rak and less about the coaches from the beginning. This is a guy who envisioned being a one-and-done when he came to SU. He wasn't prepared for how hard he'd have to work to bring his skill level up to the level of his physical attributes, or for how competitive things are in the post at the collegiate level. He didn't show the right level of game concentration, and frequently made defensive mistakes. He didn't always play as hard as he should have--hence the subpar rebounding totals his first couple of seasons.
This year, he is focused. He is dialed in. He's demanding the ball, and chasing every rebound like they belong to him as soon as it leaves the shooter's hand. His work ethic and skill level are now at the same level as his athleticism. And the net result is that he's become a player who is formidable as hell.
Is it up to the player when the team isn't feeding the post? If you're a guard you can shoot yourself out of trouble - not so much in the post.
We are talking about a kid that had an extremely short leash - if you missed your first shot or two and repeatedly went to the bench, in extremely limited touches mind you, you're probably going to be hesitant on offense. Defense is what keeps you in games - that's what you're taught.
If he started a game with a couple misses like he had in the 35 point outing against Ga. Tech he may have seen the court for all of 4 minutes more in the first half.
I'm not quite clear on what "drifting around the court" means to be honest. He was always posting up.
His rebounding totals per 40 minutes have gone up, but not immensely. They actually barely top his per 40 numbers as a Frosh. He's up about 2 from Soph/Junior year, but 1.2 of those come from offensive rebounds. A decent amount of that could be coming off his own misses around the rim - who knows though. More shots at the rim, and less threes than years past, also probably means more long rebounds. This year we aren't as reliant on threes so we could assume there are more balls in his area to be rebounded in general.
At this point we see him demanding the ball more because he's getting hammered in the post. The skirmishes we see down low are because the defender is more aggressive in guarding the post - when he wasn't a threat, you didn't have to fight down low - he was the 8th option on offense. It will always LOOK like he's doing more to demand the ball - but that's a byproduct of him scoring and having to fight much harder to get position. In years past nobody was killing themselves to keep the ball from going into the post because we were never going to throw it in the post anyway.
I always read SWCs recaps for comments about Rak, because I think we misused him and I've brought all of these up multiple times so this is nothing new. However, for the sake of repeating myself again, last year JB said we should get him more touches in the post - we never did.
This year he said he had some of this in him last year, but we never focused on him. Maybe JB's lying on his radio show - who knows.
I do find it hard to believe anyone thinks this kid had a talk with JB about being fiery and a team leader and suddenly decided to DEVELOP and deploy a plus/plus skillset with each hand and score the ball. It would be akin to BJ showing up next year with the same PG skill set as B. Edelin because JB told him to do it up and try harder.
No way to ever know how much he could have contributed previously - but I'm comfortable assuming it was far more than what we got. Could be wrong though - it's an unknowable.
