IMO that doesn't make much sense. Not everyone would have been able to play sick. A few players wouldn't be able to go. I don't recall anyone being out. Also if kids where sick that gives Dino MORE reason to take out the starters in the 4th Q. Putting players out there who are sick and down 38-3 is dangerous.
I feel like this is an internet rumor trying to explain the What loss.
EDIT
Cunningham did not play the 4th Q. Louisville called off the dogs. There was no reason for us to play our starters after that point. If they were sick on top of this, that is totally irresponsible of DIno. If the team was sick that helps explain why we stunk, but it makes Dino's decision making much worse.
