Dykehouse Stadium in BrookingsSouth Dakota State vs. South Dakota predictionPaul Cifonelli, Argus Leader: This prediction has worn on me for a few weeks, and it’s finally time to put pen to paper.To start, this game is perfection. It’s a big rivalry spot between two in-state teams competing for a conference championship and a bye in the FCS playoffs. It’s happening late enough in the season where the stakes are clear and obvious, and a loss for either side will leave them with serious work to do in a short amount of time.Then comes the coaching aspect. It’s South Dakota head coach Matt Vitzthum’s first game as a head coach in the series, and South Dakota State head coach Dan Jackson’s second. These two get to make their own mark on the rivalry, and any win will be a season-defining one.These teams appear different on the field, yet they’re both undeniably elite. South Dakota State embodies more of a hard-nosed, grinder attitude than South Dakota. I mean, the Jackrabbits have been coming out to “Blind” by Korn.South Dakota plays a similar brand of football with their explosive run game and play-action passing, but the Coyotes stretch the field vertically a whole lot more.This game has all the potential of a low-scoring grind. Both defenses can absolutely play in those games, and we’ve seen that. All this is to say I’m going with the home team. Both South Dakota State and South Dakota are undefeated at home this season, and putting freshman QB Austyn Modrzewski into this spot feels like an incredibly tough assignment. If he gets the Coyotes out victorious, we should probably have the Jerry Rice Award on hand for him.South Dakota State QB Chase Mason has been there, done that in big games. He’s got a next-level arm, even if the results haven’t been eye popping this season. At the end of the day, he’s going to make a play or two that will cement his legacy as a Jackrabbit and send SDSU to victory.South Dakota State 24, South Dakota 21This article originally appeared on Sioux Falls Argus Leader: How to watch South Dakota State vs South Dakota football today, time
