Rettig split work with competitors Chris Laviano and Gio Rescigno through two practices. He wants to showcase improvement to new coaches while he learns new offensive terminology and a no-huddle attack.
"Everyone's getting better," Rettig said. "Everyone's getting into the offense. Everyone has a great attitude at practice. No one is walking. Everyone is running. Everyone is doing everything right and we're working hard."
Offensive coordinator Drew Mehringer praised Rettig's progress based on the first two practices.
"Hayden has come out and thrown the ball very, very well," Mehringer said. "He's had, honestly, from where I thought he would be, he's practiced better than I thought he would, which is very encouraging."
