I had read in the Walter football draft rumors that the Eagles were looking to trade Fletcher Cox for a chance to get Marcus Mariota. Let's say they give us Cox and a 4th, we give the 27th. Would you do it??
Here is the link to the rumor

The issue in a trade like this is it is effectively a 1-year rental at low cost with an option to get a second year at a transition tag cost and the opportunity to franchise him thereafter.
But the key to understanding the economics of the deal is that he is really only cheap for a year and then you have to pay him as a top player in the league. That's not an issue for a team with tons of cap space but it does become an issue for a team like us that is pushing up against the top of the cap who already have in essence a top paid QB, top paid WR, top paid DE and top paid LT. You can only fit so many top contracts at once on your roster before you are strangling your ability to field a competitive roster across the board.
So if I'm looking at this deal I'm only doing it if I can extend Crawford for a reasonable deal and if I know that I'm probably going to let Hardy walk after this year if Cox plays like he did last year.
