Shakir has the highest catch rate in the league for wide receives: 84.6%, with a 15.3 YPC. That's terrific. Gabe Davis has a higher YPC average (16.6), but his catch rate is much lower (56.9 vs. 84.6).
If I'm Allen, I'm looking for Diggs, Shakir, Kincaid (79.5), Knox, and Cook. The Bills should probably keep Davis out there for his run blocking and occasional deep shot when he's single covered, but bench Harty and Sherfield. Neither is contributing to the pass game.
Too bad they don't have a George Pickens-type deep threat. Then they'd be cooking with gas.
