It's ridiculous the money some of these busts run off with.
They should play under incentive based contracts. That way if they see alot of playing time they would get paid accordingly. If they didn't get alot of playing time, their football life expectancy wouldn't go down much because they didn't take much contact.
Add in injury clauses that would gaurantee them a certain amount of money should they sustain career threatening injuries and there's no reason for them not to earn their 'big' contract.
