Today a possible trade between Colts and Bills was published on this site and I think that it is possible that it happens in the way described. What if the Colts were liking a lot a prospect and asked for a second round pick instead of a mid round pick or if the GM didn`t want to lose it's starting LT. So I thought about other trade.
In my latest mock, http://walterfootball.com/mocks/publishedmock/64482 , the top 5 would be:
3 - Chubb
5- Nelson (Dolphins trade up).
If the Browns had a QB that they prefered I think that they would take him on no1 just to make sure, so probably Barkley would go to NY or Indy. Of course Cleveland wouldn't be able to get their RB and at least two of the remainig top QBs would be available at the fourth pick.
I think that is the right spot that Buffalo could trade up because Browns could change the history of the franchise if they manage to get impact players on all of the possible three first round picks , including a potential future franchise QB.
As for Bufflao Bills they would draft the QB that they needed and manage to retain the starting LT because the trade value drops a lot from the third overall pick to the fourth, the difference is of a MID SECOND ROUNDER. In this scenario a third round pick could be enough to get the deal done as Cleveland doesn't need more Day 2 picks.
Browns fans , would prefer:
A) Barkley and a QB that could be not the no 1 on the board of your team.
B)The prefered QB of the staff and Minkah Fitzpatrick
C) The prefered QB of the staff , Derrius Guice/Sony Michel , Carlton Davis/Donte Jackson and a 3rd round pick.
Honestly on talent basis A is the best but we don't know if the staff likes all of the top 4 QBs. Honsetly Courtland Sutton or Tremaine Edmunds would be nice selections instead of a RB, but I think that they will be draftedon the top20. Also is read about Fitzpatrick and I remember of Jalen Ramsey on the 2016 Draft coming out of FSU. A special player that could play as a safety or a corner. Obviously I know that they have different characteristics but the talent is similar.
