as selfishness - that's the extreme (can you say, cough cough Demarcus Cousins and Carmelo Anthony) - but there are many levels to this in sports. You've got players that were all-stars before coming to BYU, and there's a certain amount of confidence and yes, bordering on arrogance that makes them great players.

They TRULY think they are "all that" and that they are TRULY better than the next guy. It's what you want to some degree in your players, and what makes players like Danny Ainge and Jimmer great players, to an extent. Deep down, they really do think they are better than the other players on the court in many ways. But, it can be a weakness if not held in check. In their own minds, it is very easy for a sense of responsibility to "help" the team, and for confidence in oneself, to evolve into something else, that seduces a player into the "I've got to be the guy" mentality, or "I've got to take the bull by the horns, and make something positive happen." As coach Rose put it, "OK, hey, it’s my turn and I’m going to be the one to get this done." Although the "it's my turn" part takes it to another level.

It's seductive to some degree, and young players either need to come to grips with it, or fail as a team, and only succeed as individuals. Guys like D Cousins are the extreme, where they take it to such a level that they actually resent other players even succeeding at all, as D. Cousins and C. Anthony did with Jimmer. Then, they have enough talent to succeed as individuals, but the team almost never does succeed.
