I will start by just saying this is a very winnable game.
Don't get me wrong, Michigan State has a lot of playmakers on offense and defense. QB Kirk Cousins, RB's Larry Caper and Edwin Baker, WR's Mark Dell and Keyshawn Martin, TE's Dion Sims and Charlie Gantt, on offense. With DL Jerel Worthy, LB's Greg Jones, and CB Chris L. Rucker, on defense.
The Spartans entire season rests on the guys up front, and after watching the Spartans spring game live and on TV, they have serious issues on the offensive and defensive lines.
They need a real pass-rusher on the edge, and they need people who can open holes for the RB's. Some of this will be fixed by having linebackers blitz the QB, but this may or may not solve the problem.
There are two reasons this game is winnable for Michigan.
1. Michigan's offensive line should be able to control the line of scrimmage.
2. MSU should not be able to contain Mike Martin, Ryan Van Bergen, Will Campbell, and Craig Roh.
This game came down to OT last year with Michigan playing with a freshmen QB in his first ever road game. This year, the game is in Ann Arbor and should be another close football game, again winnable.
