I don't get why people assume that player X (VY, TJax, Freddy, etc...) would run the wildcat better than Smith. Granted it hasn't done much yet, but they showed it yesterday and now teams need to prepare for it a bit. I too would like to see Smith throw out of it at least once to keep the defense honest, but they may be setting that up for a key moment down the road.
And the whole use that money to sign a WR, LB, QB is so silly since A. The Bills are not up against the cap, and B. there are really not any players out there to improve the team.
