And stay humble and hungry as we prepare for this next opponent.”The Hoosiers (3-0) returned from their first road trip with a 42-13 trouncing of UCLA.Charlotte (1-2) needed a comeback from 17 points down in the second half to upend FCS member Gardner-Webb 27-26 last weekend.Against Indiana, Trexler Ivey will be Charlotte’s third starting quarterback of the season after injuries to Max Brown and Deshawn Purdie.Ivey is not a newcomer, having thrown for 1,263 yards and four touchdowns with 10 interceptions last year.”He’s tough mentally, tough emotionally,” Charlotte coach Biff Poggi said. “He makes the right decisions, and our team has a tremendous amount of confidence in him.”
