VERMILLION, S.D. (AP) — Aidan Bouman threw two touchdown passes, Charles Pierre Jr. ran for two scores and South Dakota rolled to a 42-17 win over Northern Iowa on Saturday. Bouman was 17-of-20 passing for 284 yards and Pierre carried 21 times for 105 yards as the Coyotes (5-1, 3-0 Missouri Valley Football Conference) scored on their first six possessions except for a one-play kneel-down to close the first half. The Panthers (2-4, 0-2) took the opening drive 75 yards, capped by Tye Edwards’ 1-yard plunge. They went 70 yards on their second drive, taking a 10-7 lead on a Caden Palmer field in the opening seconds of the second quarter. Bouman had a 27-yard catch-and-run connection with JJ Galbreath and 49-yard catch-and-run with Travis Theis out of the backfield as the Coyotes quickly countered the scores. Theis scored on a 3-yard run and backup quarterback Nevan Cremascoli found A.J. Coons for a 37-yard score and a 28-10 halftime lead. Pierre had touchdown runs of 1 and 20 yards in the third quarter. The Coyotes, ranked fourth in the FCS coaches’ poll, piled up 513 yards and controlled the ball for 35 1/2 minutes. Matthew Scheckiman and Jaiden Ellis-Lahey hooked up for a 50-yard touchdown in the third quarter for the Panthers. Scheckiman was 18 of 26 for 250 yards with an interception. ___
