The upset of the season so far has been Louisiana-Monroe's overtime win against No. 8 Arkansas last week, and in case you didn't notice, fourth-down conversions were a big part of it. The Warhawks scored their final three touchdowns of the game on fourth-down plays.
There was no choice but to go for it on the first two of those three, but on the game-winning TD, ULM head coach Todd Berry took a chance. Mark Schlabach wrote earlier this week about part of the inspiration behind Berry's decision, and that roll of the dice, probably wasn't too surprising to people who have been following his program closely.
He's been the head coach at Monroe since 2010, and during that time, only two teams have attempted to convert on fourth down more often than the Warhawks. Berry is among a small group of coaches whose opponents must always be ready for anything when it's fourth down.
These five, in my opinion, are the most dangerous in this situation.
