4 Detroit Lions who need to step up their game in Week 15 vs. Denver Broncos

2. CB Cameron Sutton

If not for Jacobs' aforementioned struggles, there would be more of a spotlight on Sutton. His overall PFF grade for the season is only a couple notches above Jacobs' (59.7), and he has zero interceptions, just three pass breakups and a 101.2 passer rating allowed. Not what the Lions expected when they made a significant free agent investment in him to be their No, 1 corner last March.

This week Sutton is likely to see plenty of the Broncos' wide receiver who has the same surname. Courtland Sutton has 10 touchdowns this season, while averaging 13.2 yards per catch. Check out these efficiency metrics for him, courtesy of Player Profiler. He also has a 30-plus yard catch in five straight games.

Expected Points Added: +38.0 (20th in the league)
Quarterback Rating Per Target: 123.9 (8th in the league)
Contested Catch Rate: 54.5 percent (15h in the league)

On passes of 20-plus yards downfield, per Pro Football Focus, Sutton has a 60 percent contested catch rate (third-best in the league), which matches perfectly to Russell Wilson's frequency (13.8 percent; fifth-highest in the league) and proficiency (93.8 PFF grade) on those throws this season.

The Lions' secondary will be tested down field on Saturday night, due as much to their struggles there lately as the Broncos' not being afraid to launch a deep ball once in awhile. Sutton has to find a level he has not had this season-or it could be a very long night for the Detroit defense.
