Murray I think is just a terrible fit for this offense. He's much better of running it under center but we barely do that. He's also bad in terms of yards after contact and doesn't really make guys miss. No jump-cut ability to speak of, he just lowers his head and runs. His game is honestly ancient and it's no wonder why his snaps have gone down.
Freeman has gotten faster but he's in the same boat. He does have solid cutting ability, angles, and making guys miss but he's lost more than a step at this point in his career. Some people have said we should bring him back next year as a No.3 but I think we can do better in the 4th or 5th round of the draft.
I think EDC tried to address the RB position but there was no one really available. I think Texans claimed Royce Freeman and the Dolphins claimed Philip Lindsay so we didn't really have options. I wouldn't trade a draft pick for a rental when we could get someone better in the later rounds of the draft.
I'm more upset at Roman and Harbaugh for not finding a way to get Ty'son more involved, even with his issues at least he gives you something the other guys don't. Maybe even Nate McCrary could have been more involved but at least someone with burst and speed so you can at least make the defense respect the run game more.
