Mo is a tremendous addition to our depth. He works hard, blocks well, holds on to the football and forces defenses to keep an eye on the edges. I'm not sure what more you'd want from a guy who is essentially the #3 at that position.
As far as him not being utilized correctly, or the play calling -- Brandon Saine is running out of the very same offense and piling up a pretty impressive highlight reel of open field runs.
Edit: I'll go along with the rest of the class and agree that the line has done an atrocious job at times of keeping defenders out of the backfield on running plays. There really isn't much you can do when you're hit right as you get the ball.
Not every player translates from high school to college in the same form. Some guys are better at the next level (T. Smith), and some guys go from hero to role player. Others take time to develop and keep at it, or need more time in the strength and conditioning program.
As far as the stutter step "working" in high school and not in college, come on, Gator. College defenders are faster and smarter. The same move that makes a high school linebacker hesitate won't make a good D1 linebacker bat an eye, and he's coming full steam 40 pounds heavier and with more speed than a high school corner. The schemes are better, players play their assignments, tackling is more sure, and so on. Blaming OSU for somehow wasting Mo is ridiculous. If anything, he's a better and more complete back for playing here than he would have been at UF. All Meyer would have done is spread him out and turned him into a fifth WR. I know that it's an alien thought to you people now, but running backs generally run with the ball, not quarterbacks.
