'Give Sean McDermott credit for throwing a good challenge flag in the second quarter. The Bills’ coach saw Denver receiver Emmanuel Sanders bobble the ball as he went to the ground, and winning the challenge wiped out a 44-yard gain for the Broncos. McDermott seemed to be a little slow in using his timeouts at the end of the first half, but Hauschka bailed him out by hitting his 55-yarder. Offensive coordinator Rick Dennison called a good game in getting Taylor in position through designed rollouts to find open receivers.'
