From what I've seen of him on tape(2 games) I don't trust Franklin at MIKE. He might be better suited for WILL, IMO. Skai Moore and maybe Walker will probably be MIKE for now, unless we claim somebody else after the roster cuts. Walker can also play some SAM... Adams, Goode and Morrison if he stays are the others I expect to get snaps at SAM.
Leonard, Franklin and Moore(if he doesn't get the start at MIKE) would get snaps at WILL.
In general I don't love our MIKE position at all. Skai might develop into a good MIKE, because he's got pretty good instincts and has great coverage skills, but he needs work in the run game. IMO we still are in desperate need of a starting quality MIKE.
