Let's see, high school career rushing yardage leader 12,124 yards, in his first season as the team’s full-time starter at Alabama, most probably the Heisman Trophy winner as well as in contention for the Maxwell, Walter Camp and Doak Walker Awards, a leading candidate for first team All-America honors, rushed for 1,458 yards to rank second nationally, leads the SEC in rushing in conference games with a 166.1 yards per game average, averaging 178.7 yards per game against ranked teams, averaging 101.6 yards per game after contact, leads the nation in rushing touchdowns, has seven 100-yard rushing games this year and three 200-yard games...
I'd guess he'll have a Marcus Allenish NFL career translation - 10,000+ career rushing yards, 5-6 Pro-Bowls, Pro Football Hall of Famer.
