Why did Frank Ragnow retire?
Ragnow retired earlier in 2025, citing his health and family as reasons for stepping away from the game.
"I’ve tried to convince myself that I’m feeling good but I’m not and it’s time to prioritize my health and my families future," Ragnow wrote. "I have given this team everything I have and I thought I had more to give, but the reality is I simply don’t. I have to listen to my body and this has been one of the hardest decisions of my life."
