Aikman loved Romo as well but he would never pull any punches about his game and he does the same with Prescott. Too many see it as being critical of the player and it's not, it is only a part of their game.
He called out Romo's ball protection and he's called out Prescott's as well. As well as other QB's he's seen over the years.
Prescott's inconsistent accuracy has been a subject for two years and Aikman didn't bring it up. He was asked about it and answered it honestly when Johnson put him on the spot. And Jimmy was looking for the answer he got. The irony is Aikman's selling point coming out was accuracy and Jimmy decided to use a supplemental pick on Walsh. So, accuracy isn't the only measurement.
What seems to be lost on some is that not one ex QB or coach has come forward that accuracy isn't a problem or is solvable between college and the pros. Why in the hell does everyone think Prescott was rated no higher than the 4th round and his own team wanted two other QB's ahead of him?
