It may sound like I'm being unfairly critical of Marlon but I'm convinced he just is not an adequate back for Nebraska. All you have to do is look at the numbers
How about this:
He rushed for 1019 yards last year...but close to half of those came against Nevada, Ball State and Iowa State (442 all told). Against those three teams he averaged 147 yards a game. In the other 9 games he only managed 577 yards (64 yards a game).
He rushed for 114 yards a game versus non-conference teams last year but only managed a weak 70 yards a game versus Big 12 opponents.
Finally, last year when going agains run defenses ranked in the bottom 50 of the NCAA he ripped off 424 yards with 106 yard a game averag but when playing against run defenses ranked in the top 50 he only ran for 595 yards for a 74 yard per game average. These numbers include less than stellar numbers against Texas A&M (23 yards), OK State (66 yards) along with 15 rushing yards against Kansas and 33 yards versus USC.
If the opposition is medicore (or worse) Lucky is your man...if you want to really establish a running game versus real defenses...find someone else.
Incidently...for reference in case you want to know...here is the final rankings in rush defense for the opponents and Lucky's rushing totals
Nevada - #79 - 233 yards
Wake Forest - #17 - 90 yards
Ball State - #99 - 102 yards
