I think the bigger picture is this. If Fields keeps playing just like he is right now, no improvement but steady, Wilson will not see the field this year and no way he signs back with us as a backup. so he will be gone to the first team that offers him a starting position and we get nothing. Trading him even for a second rounder makes huge sense in that regards.
You also have to factor in that even if Justin goes down there is no guarantee that Wilson's calf will hold or something else may go wrong and again you get nothing. People are Remembering Wilson from Seattle he is not that guy anymore.
if Fields is a bust as a starter he has at least proven to be a good backup. maybe you can trade for a franchise QB next year but also have the draft capital to get a star wide out in the draft.
I just think that if the Dolphins are willing to give up a second or more for Wilson it opens up unlimited possibilities for us.
I know we have a tremendous defense one of the best in league history so far, I am just not sold that we have the offense with either Fields or Wilson this year. The oline is still kind of a mess, we have on idea of Najee's injury yet, who knows how long Warren will be out and we still don't have a stud #2 receiver in my opinion.
It's just my personal feelings that we are still a year away from being a serious threat to win it all.
