Respectfully, there are professionals who cleared this young man to play. By your own measure you contradict yourself. Even moreso because SU's MD has a history of being over cautious and refusing to allow kids to play who go one and play elsewhere without issues.
Additionally, the ultimate decision belongs to Steven. Not dad, mom, doctors, this board or Syracuse. Steven can leave and play elsewhere which defeats Syracuse's position on over caution.
We all agree that Steven's health is what is important but he has two doctors clearing g him and one doctor saying that he is "uncomfortable" which is no measure but an emotion. This emotion is what SU's MD bases his decision to DQ Steven. In short, emotions are ruling the day, not medicine, science, reason and choice (Steven's).
