Former Nebraska RB Braylon Heard will transfer to Kentucky— Joe Schad (@schadjoe) April 11, 2013
Braylon Heard also considered Pitt. Heard will sit out this year then have two years of eligibility.— Joe Schad (@schadjoe) April 11, 2013
Braylon Heard has family near UK. This a big get for Mark Stoops and co.— Joe Schad (@schadjoe) April 11, 2013
This is a very big get for Kentucky. Heard was the #5 running back in the country in 2010. He played for Nebraska in 2011 and 2012, and will have two more years of eligibility left after his year in residence. Heard was part of the 2010 class technically, but did not enroll until 2011:
Heard signed a letter of intent at NU in February 2010, but he failed to meet the NCAA’s initial eligibility requirements and did not join Huskers last year.
Heard was slated to move up to the #2 running back on the depth chart at Nebraska, and by the time he puts on the Blue and White, he will be a mature player ready to compete for the starting position immediately. He will have plenty of competition for the starting spot if things stay as they are, however, but he would be the highest ranked recruit that Kentucky has at the position.
Heard's commitment will shore up the backfield for the next couple of years. It is one more step in Mark Stoops' rebuilding of the moribund Wildcats program, and one of his highest-profile successes so far.
