Keyon Lawrence has left the Mizzou basketball team (stories here, here, here, and here), and I'm not sad to see him go. It's a tough go-around whenever a new coach comes into the fray, and that's what I think is going on here. Lawrence, an athletic guard from Newark, NJ, was recruited by former coach Quin Snyder, but he got to play for a much more demanding Mike Anderson. When a coaching change happens, there's going to be a few players who won't fit the style of the new coach, and a bad match ensues. The match looked like it might work out in his freshman season, but that was not the case last season when Lawrence struggled with his confidence early in the season. He seemed to regain it in the latter part of the season, but it's obvious now that the match wasn't going to work.
When a player initially expresses dissatisfaction with a program, it's not a bad idea to try and sell him on the program. This depends, of course, on the particular situation. With a player as talented as Keon, the strategy is to try and convince him to stay around, initially. But when a player repeatedly expresses his desire to leave, there is no reason to keep him around: the player knows that it's a bad match and it's best for him to move on. If he does stay around, chances are he will be a cancer and will bring down the team. It's best to let him go.
I wish him well, and I think this will work out better for both parties in the end (it usually does).
