Just when it seems you have talent and depth at one position, things change quickly.
Ray Helu and Quentin Castille seemed like the perfect one-two punch for the 2009 Nebraska Cornhuskers.
Bo Pelini announced today that Castille, the junior running back, was dismissed due to violation of team rules.
Castille made incredible strides last season, when he rushed for almost 500 yards on just over 100 carries.
Castille was one of the prime reasons that Nebraska was able to beat Clemson in the Gator Bowl, as he rushed for 125 yards on 18 carries.
Now, Nebraska must decide if redshirt freshmen Collins Okafor or Dontrayevous Robin are the solution for the No. 2 spot.
It wouldn't shock me one bit if true freshman Rex Burkhead was elevated to the No. 2 spot behind Helu.
Burkhead was a huge signing for Pelini and Nebraska last year. A four-star prospect according to Rivals, Burkhead seems to have the tools to be an impact player.
This is clearly a major blow for the Nebraska Cornhuskers.
Helu and Castille were expected to ease the burden from junior quarterback Zac Lee, who's never started a game before.
With the start of the season just two weeks away, it will be very interesting to see how the team responds to this adversity.
The team already lost starting tackle Javario Burkes recently and now Castille.
Hopefully, Helu and his often tweaked hamstring can stay healthy and lead Nebraska back to the Big 12 championship game.
