I'll try a better fit for MM. Trindan Holliday for LSU. Short stature but who can fly. I still think MM can be used in the slot (along with Scott) like Percy. BJS is already bigger than Harvin was, but they are extremely similar in the athleticism they bring to the field. Scott's size though will allow him to excel on either side of the ball.The way you are all describing the way we'll use him is exactly how Im expecting we want to use Burton Scott.
I think they'll give Maze a chance at receiver and special teams, and maybe use him in some trick plays. Because I think Burton is the Percy Harvin type here playing a bit of RB and slot.
MM's lack of size will keep him limited to the return game and specialty sets.
Fun thought: I imagine if they both line up at the same time, some defenses will be really worried about matchup problems. Speed kills.
