Spiller is a major surprise, I will admit thinking he was a bust like many.
Now it will be interesting to see what Nix & Gailey will do. If they can co-exist, they will be an amazing 1-2 punch. The other school of thought is to trade one to get more draft picks, or players, especially for defense. I would assume Fred Jackson would be exposed because of age and his peak trade value. I do love his play and immense heart!
Finally some luxury problems for the Bills, I hope they handle this properly for maximum value and output.
