Sounds like NO got ripped off
I think it was kind of a win/win. The Saints get a pro-bowl caliber center and get some cap relief. They move up from the 4th round to the first. Seahawks get a top notch receiving TE without damaging their cap too terribly much and they preserve what will probably be a 3rd round compensatory pick in 2016 due to the loss of Byron Maxwell. Had they signed a player instead of traded for one they would have lost that compensatory pick or at least had it downgraded to a lower round. It's a pretty good deal for both teams I think
