1. Yes
2. It depends on how many years the player has in the NFL. I think the cutoff is 4 years. Trent, having less than 4 years, was not guaranteed any portion of his contract. (After 4 years, if a player is on the roster on opening day they are paid through the full year regardless.)
Your gut - I wouldn't put it past Ralph, but I seriously doubt any team offered anything in draft compensation. After all the talk of teams who would put in a claim, it seems like most didn't.
