Incentives.

[Daseal]

In the Brunnel thread I read that incentives don't count against the cap. If this is true why don't we pay players in silly incentives that they're nearly bound to make? Are there rules stopping this, would the NFLPA have a fit? I'd think teams would lace contracts with easily obtainable goals for their starting players and be able to cut out some salary/signing bonus. Maybe someone can shed a little light on this for me!
