There actually was a Titans team at 12U last year, and 11U the year before, coached by Steve Vogel (non-dad coach). Some players on that team are on the 13U Titans team for 2011.
I believe Tim is coaching the 14U team like he did the past year.
Alter is correct. Ayers is the 14U coach (he took over for Chance half way through last season) and Chance is still heading the program overall and coaching the 16U team. Not sure who's doing the 15U this season.
