Jets RB Chris Ivory's season: From monster to ghost

Reviewing the New York Jets' 2015 season, position-by-position:

Position: Running back

Overall grade: B

Individual grades: Chris Ivory B+, Bilal Powell B+, Stevan Ridley D, Zac Stacy D, Tommy Bohanon C.

Summary: Ivory had a strange season. There's no other way to put it. For the first six weeks, he was one of the premier runners in the league. After that, he flashed elite form on occasion, but he wasn't able to sustain it. By Week 17, he was relegated to a part-time role and had only six carries, one of the coaching moves that will be talked about through the offseason. In the end, he rushed for a career-high 1,070 yards, fifth in the NFL. What triggered his slowdown? Injuries? Fatigue? Yes, those probably were factors, but let's not overlook the blocking. In Weeks 1 to 6, Ivory averaged 2.73 yards before initial contact, according to ESPN Stats & Information. After Week 6, it was only 1.82. Maybe he lost some burst, but most of the decline can be attributed to inconsistent blocking.

Powell's value was on display in the season finale, even if he wasn't. Without him, the offense was out of rhythm, especially on third down. He set career highs in catches (47) and receiving yards (388). He probably would've finished with 60 or 70 receptions if he hadn't missed five games due to injuries. He was the most underrated player on the team. ... Ridley, never able to shake the rust from his knee surgery, was a disappointment. He was a half-step slow and tentative at times, not trusting his blocking. ... Bohanon had only six touches in his fullback spot. As a blocker, he was average.

Noteworthy number: 535 -- the number of rushing yards with four wide receivers on the field. It was a league high, 413 yards more than the next team.

Playing-time percentages (based on 1,114 snaps): Ivory 49, Powell 33, Bohanon 24, Stacy 13, Ridley 8.

PT analysis: Todd Bowles doesn’t think he overworked Ivory. The statistics support the coach's claim, as Ivory was 16th among running backs in total snaps. You have to be careful with him because of his violent running style; he needs to be managed. Powell would've been close to 40 percent if he had stayed healthy. The bulk of Stacy’s work came when Powell was banged up. He got hurt when Powell returned. Ridley never found a niche, which made the decision to start him in the finale all the more surprising.
