I think there's a chance that Ruiz is the best player on the team. Certainly, on offense, he's the most irreplaceable. It's funny. 4-5 years ago, a Michigan offensive lineman being irreplaceable signified a lack of depth. Thankfully, that's been fixed to the point where with Ruiz that just means that the back-up and him is the difference between "maybe All-American" and "maybe All-Big Ten honorable mention."
