The Giants cut ties with Rashad Jennings in the offseason, and didn't add a noteworthy running back. That makes second-year back Paul Perkins the favorite to start, and there's some sleeper appeal there. But the fifth-rounder didn't have a great rookie season.

Although he was more effective than Jennings last season, Perkins was also pretty ordinary. He averaged just 4.07 yards per carry, which is a pretty mediocre number -- definitely no indication that he'll be a breakout player in 2017.

Since 2000, 61 other rookie running backs have received at least 100 carries in a season. Only one of them averaged a lower yards per carry average than Perkins. Most of the other backs in that general area have gone on to be complementary backs at best -- not guys to build a running game around. T.J. Yeldon is another recent example. Granted, one of the league's elite backs, LeSean McCoy, was only slightly better as a rookie (4.11).

Perkins was working behind a poor offensive line, and the Giants' offseason approach suggests they're comfortable with Perkins as the lead back. But he's not a sure thing.
