For the record, if I were king for a day, I'd prefer to see more judicious substitutions [in general] as well. I'd also prefer to see us mix defenses, press more, and use our generally elite team athleticism to force the action instead of allowing teams to shorten the game and hang around... but all of these topics are side-discussions for another thread.
The ironic thing about our respective positions on this topic is that I confidently predict that this year, all three of last year's frosh will find their way into the rotation this season. I expect Roberson to start and be a major contributor. I expect BJ to be this year's sixth man / super scoring sub that we lacked last year, and for Patterson to carve out some consistent time in the backcourt, despite the fact that many posters overlook him as a potential contributor. If those guys were all the players they'll be heading into this season last year, I honestly believe that JB would have found minutes for all three in what would have been a 9-10 player rotation [instead of 6-7], which would have partially alleviated some of last year's systemic team problems.
But it wouldn't have addressed all of the team problems, nor been a magic bullet to correct the team's limitations. BJ was simply too physically underdeveloped and didn't shoot well enough when he did get run. Roberson really was set back by getting off to a late start--and as much as people would like to pretend otherwise, that delayed start really screwed up his entire year. Maybe he would have helped, but then again--what did he shoot from the field again? Would that really have improved the team's offensive malaise, or would it have exacerbated it further? We desperately needed a backup point guard, but does anyone really think that force feeding the trigger happy Patterson some minutes at lead guard would have helped the team be better? Come on.
For that matter, does anyone REALLY believe that if Dashonte Riley had gotten some additional PT in 09-10, that he would have somehow morphed into a more capable player? He might have been a bit more comfortable heading into the tournament, but ultimately he was limited as sh-- [as evidenced by how the rest of his career unfolded at EMU]. It doesn't matter how much extra PT he would have gotten that season--his ability to contribute would have only been marginally better, if it tangibly improved at all. Ditto Rakeem Christmas in 2012. He just. Wasn't. Ready. Garnering a few more minutes wasn't somehow going to magically become a reliable offensive player or change his tendency to drift through lengthy stretches without doing much. He was limited that season [some might argue that he's STILL limited]--playing more might have made him a little more ready to replace Fab, but it wouldn't have erased his short comings at that point on his developmental curve.
Experience is a relevant factor, but many in this thread are over stating how important it is and then complaining about how PT is meted out in terms of how experience is adversely impacted. Equally if not more important in my book is the capability to make plays, the ability to execute, being able to capably perform systemic defensive assignments, timing / team need, etc. That's precisely why we see so many players make the sophomore leap forward in terms of readiness.
As for Dave's point above about getting "more PT for the 7, 8, and 9 so we have more depth around tournament time," it's time to start accepting the fact that JB does not coach to build depth for the future. Never has, never will. Complaining about it is as pointless as wishing for it to somehow magically change after 37 years. Regardless, while I certainly believe that JB could dole out an extra minute or two of PT to bench guys to give starters a blow, I don't think I'm going out on a limb when I suggest that there are very few examples of JB using guys in the rotation who aren't up to the task. Maybe Michael Edwards and Josh Wright. Can't think of any other examples off the top of my head. In that regard, he's the ultimate "Peter Principle" coach when it comes to the rotation: he dispenses time to each player's general capability to contribute. Those who can be counted upon to produce get time, and those who aren't ready don't.
Besides, most teams contract their rotation around tournament time, not the other way around. JB isn't alone in that regard.
