Deja vu Cindy. In our case, we've had three guys join other teams they thought were more competitive than us after committing to us, and exchanging emails, phone calls, team strategies, etc. In all three cases, they left a competitive team for a "more competitive" team (even though our team has won five straight years) that they thought was going to nationals. And in all three cases, the teams they joined ended up in last place. It hasn't been that awkward seeing them around though. Maybe that's a woman thing?
I can't complain, but sometimes I still do. Life's been good to me so far.
