To reach that conclusion, you have to believe last years team underachieved. While frustrating at times, I think last years team did well considering the talent they had and Maymon's injury. The roster has fundamental flaws with it. I also am concerned as to whether CCM is really moving in the right direction to fix those flaw. However, I don't think Golden's "weak mind", Stokes' arrival time to class, or any other random issue players may have (does McRae not like his food to touch on his plate, or maybe Richardson only showers on odd numbered dates) causes as big a problem as you would like to think.
I remember when Derrick Rose was at Memphis, some of the players made fun of him because his diet consisted mostly of candy. Just candy. Based on your world view that would show a lack of dietary discipline (not taking care of his body) and thus a lack of character or some other such nonsense. These guys are kids. Showing up late for college classes is almost a right of passage. To turn it into some type of character flaw is reaching.
Some might say that a grown man passing judgement on 19 year old strangers in a public forum is a character flaw. Just saying.
