Strength of schedule for undefeated FBS teams

An Ohio State alum friend of mine shared this with me (according to Sagarin):
Ohio State - 19
Clemson - 35
Alabama - 49
Oklahoma - 61
Florida - 66
Wisconsin - 72
SMU - 76
LSU - 81
MN - 84
Penn State - 86
Georgia - 87
Wake - 89
Boise - 111
Baylor - 120
Memphis - 123
Appalachian State - 143
I guess I'm not too surprised ours being what it is, but I am surprised at some of the ones below us being as low as they are.
