Seems pretty standard (not sure if there's individual contract language allowed that can guarantee for retirement). Chris Borland paid 3/4 of his signing bonus back IIRC.Is this common? I thought a signing bonus was in essence a team-friendly mechanism to defer cap hits to the later years of a contract, but had no idea it would operate as a penalty for early retirement by a player.
If the signing bonus isnt repaid then the remaining cap hit would all accelerate.
