Personally see four really good games. I gave my predictions in a different thread, but here are some keys I see.
West Hancock vs. Woodbury Central: I don't think weather will be a factor, so can Woodbury Central get off the field on 3rd downs, West Hancock when they are rolling can demoralize teams picking up 3rd down after 3rd down. For West Hancock can their defense step up and slow down Woodbury Central especially in the passing game, the first two rounds West Hancock has given up yards and points, and teams in the past that have beaten WH have been successful in the air.
AC/GC vs Tri-Center: This truly comes down to which defense plays better, I think both will have their hands full, and while Tri Center has been better statistically, I think AC/GC can still play defense well, the other big one for me is if AC/GC has to throw the ball can they do it? Maybe the other question is can Tri-Center make AC/GC throw the ball.
Saint Ansgar vs Maquoketa Valley: I know this sounds crazy with a Saint Ansgar game but I think the key is in the air Friday. I would expect MV to load the box, Saint has thrown for probably more yards then in the last 25 seasons, but can they do that in a big game? Then Wapsie was pretty successful in the air last Friday how well does MV throw this Friday?
Lisbon vs Madrid: First key and this is a lame one, but turnovers, when Madrid lost to Earlham they lost the turnover battle 4-0, so that could be huge. Second key for me is which star has the better game, they are completely different though. Wicker is a QB, but is essentially the RB as well, so can Lisbon make his night difficult, and can Madrid adjust if they slow him down. Then can Lisbon contain the Boots kid, he is very very fast, can they stop him before he gets going?
