I was in the let Mitch sit a year camp. I figured he wasn't ready with only one year starting at UNC. It turns out, that was correct. But it did get hard to watch Glennon every week, so I changed my mind.
Remember that after Mitch's rookie year, Fox got fired, and was on ESPN telling ppl Mitch isn't ready. That was correct, but a lot of unreasonable fans didn't want to hear it, and accused Fox of being butthurt about getting fired - he was being frank and was right.
Moral of the story: fans are not at practice; trust the coaching staff. You don't have more football knowledge than an NFL teams' coaching staff.
