*really? your NF games use an RA, is that NFHS approved or something your state is doing on a trial basis?
And, has this use of the RA improved the "block/charge" call accuracy of the officiating crew?
And, has the use of the RA affected whether such calls are reversed or sustained?
Very interesting things in MN...
