Coming off his breakout rookie year, Chargers wideout Keenan Allen opens the season Monday night in Arizona where he'll see plenty of the league's highest-paid cornerback. Patrick Peterson likely will shadow Allen all over the field.
But Peterson isn't unbeatable. Last year he allowed 688 receiving yards, seven touchdowns, a 54.4 percent completion rate and a 91.3 passer rating on throws to his coverage area. Compare that to Seattle's Richard Sherman (348 yards, 1 TD, 50.9 percent completions, 36.2 rating).
It should be noted Peterson played 100 more snaps and regularly shadowed the opponent's top wideout, while Sherman usually stayed on the left side of the field. Still, Peterson has a gambling tendency San Diego can exploit.
Allen caught 71 passes for 1,046 yards and eight touchdowns last year despite being used sparingly the first three weeks. He's a precise route runner and Philip Rivers' favorite red-zone target. From Week 5 through Week 16, Allen went over 100 yards or caught a touchdown in eight of 12 games.
Despite the tough matchup, start Allen as a low-end WR2.
