‘The Bills quarterback fired touchdown passes to a multitude of pass catchers throughout the day, the most impressive of the bunch going the way of rookie wide receiver Keon Coleman. After beating cornerback Christian Benford down the left sideline, Coleman sprung free, and Allen found him with a bullet he delivered on a line to the end zone. The pass forced the rookie WR to fully extend before he made the catch with his fingertips. The latest connection between Allen and Coleman added to what has been a red-hot training camp for the rookie.’
