Difference is I thought Leaf was going to be good in the NFL when he was drafted, I knew Manziel would suck and was not an NFL QB.. He was a higher pick too, Leaf was hyped up beyond belief and a no miss at the time so to speak. Manziel was never built like an NFL QB IMO either. Russell Wilson is not I know and around the same height but that dude has brains and actually works hard on his game and maximized his talents.
