Closing thoughts

Michigan has four running backs with experience on its roster. It’s a great problem to have, but three players will have to give way to a feature back.

Green and Isaac are excellent choices for Michigan’s top spot at running back. They were highly-touted preps in the 2013 recruiting class and could be poised for a huge year with Harbaugh at the helm.

But they have their differences. And that’s why I like Isaac over Green in a close competition. The redshirt sophomore has superstar potential and can be a force in Michigan’s offense.

Smith was considered to be a great compliment to Green, but he wasn’t able to take advantage of his playing time, giving way to Johnson’s breakout. It’ll be tough for Johnson to break into the lineup, depending on how much time he misses. Everyone heals differently, and it’s important to note this was that knee’s second ACL tear. It’s unknown if he can be the same player once healthy.
