I'm sorry, but did you watch Manuel play at FSU? He was a profound disappointment for us FSU fans, and the narrative on him hasn't changed: he's a great kid with all the tools and for some reason can't bring it all together.
FSU lost in big moments with him at the helm despite a significant talent advantage. Since he departed, the Seminoles have won a national championship and haven't lost a game... Winston, for all of his faults, is an example of what having an NFL-caliber QB can do for a franchise.
Edit: with all of that being said, I do hope things work out. He's a great guy with a lot of potential, but counting all of the seasons I watched him in Tallahassee, I'm about to enter year 6 hoping things will click for him.
