No, what Goodell said is that he is taking the lowest 4th round pick that the Patriots have, so if the Pats only have their 4th (then they would not be able to trade it), he will take that. If they aquire additional 4th round pick(s) he will take the lowest 4th round pick they have. So let's assume that the Browns end up with the worst record and both the Pats and the Seahawks make the playoffs.
There is no way the NFL issues 8 3rd round comp picks, so the Browns are not going to get a third round comp pick, so just take that thought out of the equation right now. So the Browns are going to trade the Pats there 4th round pick which should be someone around pick # 102. Pick # 102 for Collins, that sounds terrible, but wait IT GETS WORSE!! That pick is GONE, stolen by Goodell. The only compensation the Patriots are receiving for Jaime Collins is their ability to keep the 4th round pick that got from Seattle in exchange for pick #147 in 2016, which they acquired from Miami for their picks #196, 204, & 250. That is provided the Patriots go farther in the playoffs than the Seahawks. So basically they traded Jaime Collins for a late 4th round pick.
If I told you this am that the Patriots were going to trade Collins for a late fourth round pick, would you have liked that?
