Can never hurt to put another back into the pipeline. I think our philosophy is not to look to fit the mold of a previous back exactly but to use good athletic smart backs to the best of their ability. Harris-Stephenson were bell cow types, and I am never against collecting more talent on the cheap in the backfield. I think Strong is there as a change of pace or third down guy and Other Harris is a just plain bruiser (another one). in fact, it will be interesting to see whether he can be "the guy." I don't think so, but it's always fun to watch the stable develop. Before Stephenson showed he could be Damien, Damien was showing that Sony Michel was expendable (As guys here were all crying about how we lost this irreplaceable guy.)
The way the Pats still manage the backs is a thing of beauty. I hope I don't curse it with this post.
