I can't think of any QB in modern history who has ever had to overcome so much to be effective.
My concerns have lasted far longer than four pre-season quarters, just as my anti-Weeden rants went far beyond just the start of his NFL career.
Guys who come from such a simplistic offensive scheme predicated on a handful of fail-safe plays used repetitively have a huge hurdle to overcome to succeed in the NFL. When you combine that with a lack of experience at the collegiate level before making the jump to the NFL, and you throw in average physical skills (not the strongest arm, not the fastest legs), you have a recipe for disaster in the NFL.
Will there be an exception to this rule? I'm sure there may be, but the correlate effects of the above qualities has such a high failure rate in the NFL that it's almost undeniable at this point.
The difference with Manziel is, for one reason or another, his hype those who buy so heavily into the intangible traits like "winner" and "playmaker" caused his draft status to rise to vastly overrated levels.
Browns management potentially being among that group. But if I had to guess, I'd say it was Haslam with a great influence here looking to re-market the team and provide a bit of excitement for the franchise.
I won't judge Farmer on it either way, as he did such a good job netting the Bills 2015 first rounder that I'd still consider it a win at this point even if Manziel completely fails.
