Absolutely he would have helped. McGruder was an absolute non-factor offensively.
Just to be sure, we are talking about Dominique Sutton's offensive capabilities, right? Against Duke's defense no less. Yeah, I'm sure Dom would have lit them up for a free throw. 
My point was that since we got nothing from gruds, getting nothing from Dom would not have hurt us, while Dom's defense would have been far superior to grud's.
I honestly thought you were making a joke about how inept Dom was on Offense. McGrud's >>> Dom imho.
I thought Dom's defense was a little overrated the last 2 years, and his inability to do anything on offense made it that much harder on everyone else to score. McGruds is as good a rebounder, if not a little better, despite being shorter and less "long". I think McGrud's defense is solid. Who was he marking most the night? Singler? I think he did fine.
