Don't forget Penn State plucked Brady Berge from coaching at South Dakota State mid-season and inserted him into the lineup, first at 165 as he made his way down to 157.
As for the MFF's, I agree that I don't care for them. But Iowa does seem to have some guys banged up, including Cassioppi a bit. Yeah, he could have gone out there, but....
And I heard Rivera had a minor knee procedure done 2 weeks ago and had planned on MFFs after he qualified. I hadn't heard that ahead of time and was a bit miffed at the time. If true, I guess it is understandable.
My guess is Mason will get either the 5 or 6 seed. #6 would be preferable for the reasons you mentioned.
Regardless, it should be fun in 2 weeks
