Attend a skills camp with players of equal or better caliber run by professionals. Or better yet, play in a summer league composed of the same, for at least one (and preferably more) of the 4 summers attending ISU.
The skills camp idea is a good one, but like ripvdub said there aren't many of those available to college kids. I don't know why, but I'd guess it's partly because there aren't enough people to run them. Other college coaches probably can't run them because of NCAA rules about contact with college players, not that any coach in his right mind would let another college coach instruct his players. NBA coaches probably can't run them because it a violates of NBA and/or NCAA rules about contact. So you're down to guys who don't coach in college or NBA to run a camp, and I don't think there are that many guys like that who are qualified to coach Big 12 caliber players.
Playing in a high caliber summer league sounds good, but the NCAA limits where guys can play in these. I think they have to play within 50 miles of their college or hometown. I think Kansas City has a really good summer league with lots of Kansas, Mizzou, and NBA players, but that's not an option for ISU players.
Please explain to me what good ISU's post and power forwards get out of a league that is primarily a no-structure run-and-gun league where, perimiter players dominate the offensive play, where there is little opportunity to work on offensive moves or defending interior players? Particularly when the Big 12 isn't anything like that...
Big guys can work on just about everything but their post game in the summer league. Just because most guys choose to play sloppy doesn't mean you have to. Yeah, it's mostly oriented on perimeter play, but there's still plenty for the big guys to work on with rebounding and their mid-range game. It's not like big guys get to camp under the basket in the college game, so they still have to work on their perimeter skills.
By staying in town, guys can still get instruction from their college coaches (and supervision if they need it). They can take summer classes. They can build cammaraderie with their teammates.
Playing in the summer league should be a small part of a player's offseason routine. There's a risk of injury, but that's the only downside I see. It lets players work on their skills in a (mostly) organized setting. It lets new guys get used to playing with players bigger and faster than high schoolers. It exposes players to new styles, and lets them play against someone other than the college teammates they have to play against the rest of the year. It lets them do a little recruiting of the high school kids in the league (Barnes). Maybe best of all, it gives us something to watch during the summer. :yes:
