The "scared" to compete garbage is thrown around WAY too much. If a program ( heck a job for that matter) has multiple people at your level that will split time with you during your limited window available to impress and put your skills on display to bolster your resume, while another offer for a similar position gives you a clearer route to get fully immersed, gain experience, and showcase your skill set, you take that into consideration. It is called making a wise business decision.
Being "scared" to compete has nothing to do with it. I hope he chooses UNC, but if he doesn't it is not because he lacks the backbone to compete.
Totally agree!!! Pretty much any kid wants to play rather than sit on the bench, I do not blame Pierce for going elsewhere if he feels he will get more PT. BUT, PT should be earned and if you are really that good, you should be willing to take what you want rather than need it given to you. Truth is, if you are really confident then it should not matter who may be competing for your PT, matter of fact winning PT against stronger competition should substantiate your ability rather than take away from it.
