LeSean McCoy
Look, I don't think the Bills are doing too much this year. With everyone mostly healthy I'm thinking between 5-11 and 7-9. That said, and even if you put everything else aside including a seemingly improved D and and at least competent QB in TT, I just don't know how you can look at any team with McCoy at RB and say, "this is the second worst team in all of football."
The 2010 Bills were quite simply and absolutely dreadful and they still finished with 4 wins and in 30th place. I don't love this team, but it is worlds better than that team, even if "worlds" is defined as 1 or 2 more wins.
