I think it's a passing league and the Bills have a poor passing attack with Taylor. His numbers aren't bad. 300 yards is an arbitrary number that guys like Blaine Gabbert have hit this year and Taylor has not. It's as likely he can regress like Bob Griffin, Josh Freeman, Colin Kaepernick, or even Bills QB's of past like Losman, Edwards, and Fitzpatrick.
If the Bills wanna be a team like KC who looks like they'll make the playoffs and have a nice season but IMO have no shot at a SB than Taylor can be the guy.
