As stated previously, the article provides only one side of the story. And that side has a lot of holes IMO. I'm making my own assumptions of course, but the kid comes off as a bit of an opportunist, whose taken full advantage of the free-ride that an athletic scholly offers. Nothing wrong with that, except for the whining now that the gravy train has ended.
His minutes got reduced - was that because of lack of effort or commitment? He marched into Martelli's office to tell him what he intended to do. Not to ask his coach for advise. Doesn't sound like they enjoyed a very close player/coach relationship. Why not? That initial and animated meeting with Martelli is central to what really went down, but the kid conveniently leaves out any details of that conversation other than Martelli's use of expletives. What got Martelli so exercised? We'll likely never know the whole story, but maybe Martelli had enough of the kid taking and took a stand - a teachable moment perhaps.
Just because the kid says..."To be honest, I didn't want to be "that guy", the player who had bounced around to three schools in five seasons", doesn't mean he wasn't exactly "that guy".
