Unfortunately today, it's all about "play now" for those R1 QBs because everyone sees them as a savior and so few can actually do it. If Mayfield, Watson, J. Allen, et al., had a full year or two of just learning, they would probably be a whole lot better for it. I doubt that even Rodgers could have carried the whole weight of a franchise as a starting QB his rookie year and been successful.
I don't think so. I saw him close up from the 50yd line in one of his first preseason games his 2005 rookie year. Looked lost and almost meek. First thought when seeing our newest RD1 QB was "that's the guy? crap."
