Breaking down the New York Jets' roster, unit by unit, in preparation for training camp:
Position: Running back
Notable on the bubble: Zac Stacy.
Top storyline: It's all about Forte, who will be asked to replace 1,000-yard rusher Chris Ivory as the lead dog in the Jets' backfield. Forte will be highly motivated after getting the cold shoulder from his forever team, the Chicago Bears. Forte, 30, is battling Father Time and a cranky knee that sparked some concern in free agency, but he's said to be healthy and rejuvenated as he approaches his ninth season. His workload will be an ongoing story. As a three-down back for the Bears, he averaged 315 touches (rushes and receptions) per year. That's a bit steep for an aging runner, so look for a time-share system with Powell.
Player to watch: There was a noticeable improvement last season in Powell's speed and quickness. He set career highs in yards per rush (4.5) and receptions (47), becoming a valuable member of the offense. He was the ideal complement to the bruising Ivory, but the dynamics have changed. Powell and Forte have similar skill sets, so it'll be interesting to how it plays out in terms of role definition.
Training camp will be a success if ...: The words "Forte" and "fountain of youth" are being used in the same sentence.
Wild card: Robinson is the mystery man. He played well in spurts for the New Orleans Saints, but he never was able to create a permanent niche. Some people say he's a poor man's Ivory because of his physical running style. He could wind up as the short-yardage/goal-line back (fantasy alert). Don't be surprised if he starts camp on the physically-unable-to-perform list. Robinson sat out the offseason as he recovered from a broken leg, but he should be good to go in the preseason.
By the numbers: Forte said he's looking forward to having a lead blocker once again. In Adam Gase's offense last season, he had only one rushing attempt out of a two-back set, according to ESPN Stats & Information. In Chan Gailey's offense, the Jets used the fullback about 25 percent of the time. Ivory ran 122 times last year in a two-back set, which gives you an idea of what Forte can expect.
