You obviously have no idea how the Sagarin rating works. The Sagarin rating, including the strength of schedule rating, are a dynamic ratings system updated weekly.
Griffith literally lost to the only two average or better teams on their schedule. Pioneer just got blown out by Taylor. LaVille is down for them and Jimtown was inconsistent. Garrett beat WN twice, which is hard to do with good teams. Garrett beat Lakeland twice, which is hard to do with good teams. Garrett beat the breaks off of Fairfield who beat CMA who beat Knox.
It's close, and I think its gonna be a good game. I could see Knox winning by two scores if things go their way but personally I'm picking Garrett in a close one. It's not as cut and dry as you think it is.
