Agreed. I think the Bills expected Gore is more productive in the 1st half and middle of the game. Also, Gore time has been impacted by th decision to go no-huddle with a 11-12 man group
And finally, having Andre Roberts as the KR/PR and Senorise Perry has hurt the teams combination at the RB position. Roberts has taken up that 3rd RB position but has not been part of the passing game. Perry has played only special teams. The Bills can do nothing about it as both Roberts and Perry have done very well on ST.
