B. is a hockey coach for N.Y. Tech who appears to genuinely care about the futures of the students on his team, Casey Jones in particular.  I imagine him having a very even temper and a slight bit of urgency in his delivery because he really doesn't want Casey to be dropped from the team.  I would like him to sound middle aged, so nothing that sounds too old, and I'm open to accents if you have an interesting idea.  Good luck, I look forward to hearing from you!
