Well, P&G, I don't see what is so difficult for you to understand here. I'll break it down with a few real-world examples:
Rudy Gay - Jim Calhoun said he was lazy and relied too much on his talent and other reports stated that he was a little selfish. Many of these factors were evident in his first season, but he has turned the corner and it's obvious he's put a lot more work into improving his game. Also, he's connecting with the fans very well by asking for dunk ideas, which is really cool. I knew he wouldn't work with JVG because offense is his first priority, where Battier plays great defense... I also didn't know how Gay could improve his offensive game with T-Mac taking 100 shots per game.
Kwame Brown - #1 overall pick out of high school... since 2001, he's never had 2 games that compare to what Bynum has done this season so far. You could blame earlier struggles on his youth; you can only blame his boo-inciting plays now on immaturity, laziness, and propensity to throw birthday cakes.
Tyrus Thomas - applauded all NCAA tournament season for his "upside," "athleticism," "potential," "explosiveness" etc... much like Rudy Gay. However, at least I was right about him when I said Portland got the better end of the deal because (a) he was born in Baton Rouge and went to LSU - a university that has produced typically talented, but unmotivated players - mostly in football; (b) he's too full of himself and (c) is more interested in "picking up his paycheck" than improving his game.
Bynum - obviously very talented; Phil (your personal Jesus) saw this talent, but also noted some immaturity, which is why Kareem was brought in to mentor him both on and off the basketball court and probably why Bynum has been fined and benched for certain games because Phil wants to teach him a lesson. I won't accept the age card from you because both LeBron and Amare came into the league straight from high school (actually, Amare came from 7 different high schools) and made immediate impacts.
I still think Amare is immature on and off the court and needs some discipline out there because he brings the ball too low when it gets into the post and gets it stripped... that's something you never see Tim Duncan do (when he catches it high, it stays high) and Bynum rarely does it now too. It's nice when you can have a former hall-of-famer and all-time scoring leader agree to mentor your potential franchise center... if only the coin flip had gone to Phoenix instead of Milwaukee back in the 60s.
