Assuming he's at full speed, the lion's share of that effort will likely fall on the shoulders of junior Eddie Lacy, who is both the most experienced of 'Bama's stable of blue-chip tailbacks and, courtesy of his 6-foot, 220-pound frame, the most reminiscent of departed All-American Trent Richardson. But the bottom line is that the ball carriers are interchangeable: Whether it's Lacy, or freshman T.J. Yeldon, or short-yardage thumper Jalston Fowler, or anyone else on the depth chart, the priority is giving him plenty of room to run.
That said, Robinson likely will have to complete a long pass or two on the new corners to either keep the defense from crowding the line of scrimmage or make them pay for it when they do, which will be a tall order. If the Wolverine D manages to hold up against the run, though, a couple of quick strikes could be the difference in a low-scoring game.
X-FACTOR. Michigan coach Brady Hoke has been toying with reporters this week over the status of suspended tailback Fitzgerald Toussaint, by far the most dangerous weapon at the Wolverines' disposal after Robinson, but only if he's allowed to play. With Touissant in the lineup, Michigan is the only team in the nation with two returning 1,000-yard rushers in the same backfield, and Alabama has another reason to risk sneaking its safeties closer to the line of scrimmage. Without him, Michigan has no proven running threat besides Robinson, who has a big enough target on his jersey as it is.
