Nope to your questions above, but there will never be 60,000 fans in the stadium an hour prior to kickoff.
Look, there's a percentage of fans who come primarily for the tailgating, a percentage who come primarily for the game, and a percentage who come for both.
While I fall in the 3rd category, there's no way I'm ever gonna be late for the kickoff. That's why after reading the warnings about likely delays, I chose to enter the stadium an hour before kickoff. I wasn't going to take the risk, and I'm glad I made that decision.
