If GC wins Fri night it would be only be a minor upset and not a big surprise. GC and CPA may end up playing 4 times and it's hard to imagine a scenario where GC doesn't win at least one.
Based on a few common opponents and records, it appears GC and CPA are likely the favorites to go 1-2 in Region 6. Upsets will always happen, but on paper those 2 appear to be the ones to beat.
Looking down the road a bit, which is what makes these Boards interesting, MLK is lurking. No team in AA in Middle TN wants to play at MLK to make it to the boro.
