Ny, I don't think anyone has had the ability or earned enough points to buy a team yet. What most of us have done is just signed with some team until Kaplan creates the fighting Irish team.
On your players profile, you should have a contract offers tab at the top of the page. If you don't have any offers, I would go with Brown 002's strategy.
Getting a contact that good is the best way. I have run into a problem b/c my Energy is getting too low. I cannot buy a team until there is one for sale. I already have the financing in place.
