I bet you 90% of it is simple inertia. Lynch is the undisputed #1, Turbin is #2 and Michael is #3. And it is working since the Hawks have one of the best running games in the league with one of the worst offensive lines in the league. So why change? I have a feeling that coaches are reluctant to make changes unless it's obvious or necessary, this is one reason so many talents are finally "discovered" by chance or circumstance. How the hell did Curt Warner go from bagging groceries one year to winning the superbowl the next year? Did his talents and skills all of a sudden explode by ten fold in his late 20's and early 30's, or did he get lucky and get a shot?
I think this year is a no go for Michael, he will need an injury or severe sucking by Turbin to get a shot. While i think it is plainly obvious to any and all, that his talents are desperately needed for this team's offense. He would add a different dynamic to the team, another tool in the shed. A player that can break it at any second, in fact, currently the only player on the team with said ability. Harvin does too, but he hasn't played yet. We need to start the give Christine a chance group.
