The nice thing about this team is that it's built to win NOW, not in 2 or 3 years. For once, we are in a position that we don't need a high-profile rookie or someone inexperienced to come in and play at a high level. Christine Michael is a luxury, and not a necessity. He'll get his chance down the road.
Remember, he lost two years of playing time in college due to injury, so he's way behind the curve, as far as playing at a higher level. I would suspect that later in the year, he'll start handling some of the return chores.
