text: For some sports teams you have to pay over one hundred dollars. If you threaten to kick kids off the team if they don't get a grade that would be extremely hard to obtain, they won't pay hundreds of dollars if they even think there is a possibility of being kicked off the team before they have played a lot than they won't pay! It would make more sense to put a slightly lower grade that they have to meet because than the kids will see they have a bigger chance of reaching that goal. You are on the right track but don't go overboard!
