Surely, you remember the LSU running back who, as a freshman last year, steamrolled Georgia for 201 yards in the SEC championship game, then lit up Oklahoma for several long runs in the Sugar Bowl. He was listed as a preseason Heisman candidate this summer. Through four games, however, the sophomore has been mostly a non-factor, gaining just 223 yards on 49 carries. Meanwhile classmate Alley Broussard has emerged as the Tigers' more prominent runner the past two games, gaining 84 yards on 10 carries against Auburn and scoring LSU's first three touchdowns against Mississippi State. "He gives us a dimension out there that nobody else does in terms of his physical presence and toughness," coach Nick Saban said of Broussard. "We're happy to have it." Here's a theory: LSU's offensive line isn't opening the kind of holes it did last year, and the more physical Broussard is better equipped than the speedy Vincent to make something out of nothing.
