Lots of astute comments on here....I think you guys pretty much have it figured out. Our offensive line is vulnerable and our offense stalls a lot, especially if we can't get a running attack going. It'll look great one minute, and then go 3 and out for the next three possessions.
On a scale of 1 to 10, Cousins' escapability is a -3. If you can get into our backfield enough, you will probably win.
Cousins can look great at times, but then he'll just make bizarre decisions that affect the outcome of a game - like throwing red zone interceptions, or waiting too long in the pocket and getting sacked in critical situations, throwing off his back foot, fumbling the ball, etc. I love the kid, but he's gotta clean up some of that stuff in order to be considered a very good or great QB.
It just seems like MSU has a tendency to make stupid mistakes that end up hurting us a lot....In the Wisconsin game, we fumbled on the first play of our 1st possession, handing Wisky an invitation to our end zone for a quick 6 points. Thankfully, we were able to overcome that, but eventually mistakes like that will lose you games - especially on the road in a hostile environment, in the Big Ten.
