Definitely optimistic this year. I think McD is exactly what this already talented team needs.
Everyone talks about what the Pats have added. The Bills are adding at least 6-7 guys who can be big difference makers. Ragland, Hyde, Lawson finally getting a full season. Watkins back to full health, with Zay being a legit #2 and a guy I see as more versatile and dangerous than Woods. White might be a downgrade talent-wise, but I would bet that he won't have as many lapses as Gilmore. Dawkins will upgrade the line and bring some nasty attitude. And I think that new punter will even work out - Schmidt had some very bad games last year. Field position battles can determine games.
I can't wait to see a more disciplined, focused team. I love that we're close to last in some of the power rankings. I think this team is going to surprise a lot of people.
