I considered the same possibility. My first thought was that maybe the Saints have a trade agreement with a team and a new contract agreement with the player being trading and now they are making room so they can finalize the trade and contract.
Then I thought who would be good enough to command that much money, have a team willing to trade them away and be worth the cost of the trade. The first name, due to familiarity, that popped into my mind was Trey Hendrickson.
I'm sure there are other players that fit all 3 criteria that I'm not aware of. Is their a offensive lineman out there that might fit all 3? Are there any player at any other position?
