"The biggest thing (is) you can't be changing defenses every year," Carr said on the Sports Pen on ESPN 970-AM. "The players need to learn a system, and you can't learn a system if you're changing every year. (Defensive coordinator Greg Mattison's) brought in the 4-3 defense, and I think we've got to recruit some bigger players."
Rodriguez's offensive and defensive systems were predicated on smaller, quicker players. Many questioned the wisdom of using those players in the Big Ten, where tradition (and weather) generally dictates the use of bigger, stronger players.
"We've been a very, very small team for the last three years," Carr said. "In this conference, to play championship football, you need big people because you're gonna play against big people almost every single week. And when you're a much smaller team, you're gonna wear down, you're gonna get beat up, and you're not gonna be able to finish a season.
"In this conference, it's at the end of the season that you have to be strong if you're going to do the types of things and have the kind of seasons that we've always aspired to have here."
