I'll be honest. My only worry about him is transferring because of a perceived poor fit. I would assert that the fit is perfect and that everything will go wonderfully as long as he stays and keeps working (just like he has been working already).
There should be no problem here. He's really tough already, he has immense potential, he has a fantastic head coach, he's in an outstanding program, and he's attending one of the best schools in the nation.
Going pro now would be a big mistake. Transferring now would be a bigger mistake. He is exactly where he needs to be. The "system" CMP runs is extremely fluid and is versatile enough to exploit the personnel he has. Next year's team will look very different than this year's team, and it will be built around Carsen, Nojel, Matt, and our other talented players...
...as long as Nojel is here. I truly hope he is.
