Hmm . . .since I volunteered to do the 16U poll, these comments about a coach (in my case an assistant coach) not handling the poll got me questioning whether I should do one. But then I realized, a fan could have just as much motivation to mess with the polls as a coach.
I'll probably come up with some kind of excel spread sheet that assigns a code identifier to each voting coach (the code being known only to me and that coach) and then send the excel sheet out to all of the voters in a mass email each week so each coach can see that his/her vote was correctly captured.
