This was always inexorable and as easy to read as the Hollywood sign on the hill. Which 4 picks of the top 5 and what sequence is interesting but the Browns, Giants, Jets and Broncos will all have a new QB before the Colts are on the clock. The Jets/Colts trade was not about the Bills, it was about the Broncos.
The slim chance the Bills have is a trade with the Browns at 4, or if the article is true, and their dysfunctional group can only reach agreement by seeing what happens in front of them, an even slimmer possibility at 1. Both of these possibilities are very slim IMO. If the Giants somehow hate all the QBs but one, and the Browns pick that guy, I suppose something could happen. I think the overall odds of the Bills making a top 4 pick is about 2%.
