Daseal:

Obviously, the fees paid to agents vary based on the amount of services that the agent provides. (BTW one service I forgot to list up above is that many agents also do the taxes - Federal State and local - for players). The bare minimum is 4%. Many agents get 6-7%. I've never heard a number over 7.5% but I don't pretend to know the details of every agent/player deal in the league.

There was a rumor that one agent had a sliding scale rate with his clients and if he got them more than a specified number in a contract negotiation, then his percentage of the deal was higher. If that was true, that practice stopped because the NFLPA won't certify an agent who does that.

While it might sound like a good deal for the player - and it might me - it also encourages the agent to hold the player out and that might be very harmful to the player and his career. I don't know for a fact that this agent did this, but it was a very prevalent rumor about 10-12 years ago.
