Young is our only power back on the roster, and there will always be situations where nothing can replace sheer brute force.
We were spoiled by having an abundance of running back talent last year, and especially by having a back who could do it all in the way of Estime.
I do agree that we're actually in a pretty good situation at running back, that almost all of our guys are returning, and the two incoming freshmen have lots of talent, but to say that we won't miss Audric Estime one bit is an exaggeration.
That being said, if Kedren Young crashes the scene, then your statement would have far fewer detractors.
