Believe it or not the Saints won big on this deal. They get rid of a disgruntled / immature player and still get a 1st rounder albeit #32. The 1st round picks contracts are beneficial to teams; 4 years with a 5th year option.
Cooks is now someone else's problem. We know Cooks is not getting big money in NE so the Pat's are basically renting Cooks for one year at the cost of 1st and 3rd round picks!!!
I think you answered your own question. If that Tenn. deal were real obviously the Saints would have taken it.
I think it was Larry Holder on his podcast earlier this week that mentioned teams just do not give up 1st round picks on trades for WRs. It happens with NE of all teams and no one is satisfied!
