LSU Tigers

Derrius Guice is one of the nation's top non-QB candidates for the Heisman, but what else do the Tigers boast that will make their run game better than last year's mark of 233.0 yards per game (21st in the nation)? Danny Etling isn't a mobile QB, and replacing Leonard Fournette won't be a walk in the park.

Georgia Bulldogs

Big things are expected from this rushing attack since Nick Chubb and Sony Michel both opted to return for a senior season, but the Bulldogs only ranked 50th nationally in yards per game last year. With a quarterback who has as much passing potential as Jacob Eason, Georgia doesn't need a top-10 rushing attack to win the SEC East.

Tulsa Golden Hurricane

Only 19 players rushed for at least 1,400 yards last season, but Tulsa had two of them to rank in the top 10 in team rushing yards per game. However, losing leading rusher James Flanders (1,629 yards, 18 TD) will likely bring this team back to the pack.

West Virginia Mountaineers

Will Grier will give the Mountaineers some mobility at QB, but he isn't likely to scramble quite as much as Skyler Howard did over the past two seasons. Also, losing No. 2 RB Rushel Shell makes it tough to project WVU as a top rushing attack in 2017.

Old Dominion Monarchs

Leading rushers Ray Lawry and Jeremy Cox—combined 1,987 yards and 24 TDs in 2016—will be back for another season, and Old Dominion will likely be more dependent on its running game after losing starting QB David Washington. If nothing else, the Monarchs should have the best rushing attack in Conference USA with room to spare.

Louisville Cardinals

In addition to B/R's Matt Hayes' recent piece about how Lamar Jackson is becoming more of a pro-style QB this year, the Cardinals fumbled too many times last season to be regarded as a top rushing attack.

Georgia Tech Yellow Jackets, Navy Midshipmen and Air Force Falcons

Each of these triple-option offenses has ranked top-10 in the nation in rushing yards per game in each of the past three seasons, but one other commonality is that each lost a bunch of key pieces. Air Force will be without three of last year's top five rushers, Navy lost four of its top five guys and Georgia Tech must adjust to life without two of its top three, including three-year starting quarterback Justin Thomas.

Yes, these systems built on interchangeable parts are designed to withstand attrition, but that might be too much to replace. While they should remain top-25 rushing offenses, top-10 will be tough.
