Agreed. I was just expanding on what Reg was saying. He was saying people are worried that Diaz is going to follow in Richts footsteps and flip flop the QBs all season. I can't think of a single team that doesn't have 3 QBs even if some of them are walk ons.
Have you never heard the quote before(usually it is used with 2 QBs)? The quote does not mean "if you have 3 QBs enrolled at a school you have none". It is referring to teams that flip flop QBs all throughout the season or even teams that use multiple QBs in single games.
