Matthews did offer versatility, but I don't think he offered the nastiness and the power that this regime was invisioning on the offensive line.
Matthews was a great prospect, and should be one of the top technicians in the NFL for the next eight years, but Robinson has such rare physical skills and abilities that it's well worth the growing pains.
How many early picks has this regime truly missed on? Pead?
My last couple posts weren't intended to criticize Fisher or anyone else. I was just pointing out that there hasn't actually been much said negative, and to dispute the notion that Matthews wasn't versatile enough to play guard.
