IMHO there is a major differences between Jamarcus and Ryan.
Jamarcus was lazy and didn't work at his craft, He was paid millions and was a one year wonder, in college.
Mallett is a hard worker, he is a film rat, something Jamarcus never was, and he won't get paid millions until he produces.
Both are not IQ geniuses. But Jamarcus possessed a Wonderlic score in the low teens, almost functionally illiterate. Mallett has a high enough score at 26 to fit in the category of all the successful QBs; but it is toward the low end of the range. Still its higher than Terry Bradshaw and Ben Rothlesbergers scores,a pair of pretty successful QBs. Too low and you can't comprehend a playbook. They could, and so can Mallett.
Both Jamarcus and Ryan are huge, and both have cannons for arms and great size; but Jamarcus has running speed, but no shiftiness. Ryan has the same kind of side-stepping pocket shiftiness that Brady displays, but not to the degree; and Mallett like Brady, has next to no running ability.
I suspect Ryan's supposed personal "problems" are overblown. But he seems like a young boy and not too mature. Time will cure most of that.
There appears to be something else too. Ryan does not seem to be a natural born leader, and Leadership ability is a requisite quality for a great Quarterback.
