MSU stays stagnant during bye. Alabama moves up during bye.
Alabama barely beat UT and Arkansas and lost to a 2-loss Ole Miss. Their best win is 3 loss WVU.
Michigan St has only lost to a #3 Oregon, though they were sloppy against Purdue (that rings a bell). Their best win is the Huskers. You could look at the game against the Huskers as a close contest, but even then, Nebraska was undefeated and #16 at the time (currently #11 with only one loss).
I got to tip my hat to Michigan St in that comparison, but #SECBias
