All-around, definitely Gronk, since we're talking about 'prime' here, as injuries play a big factor. Graham is faster but other than not spending half his career injured, I can't think of anything else Graham can do better. While he does some things just as well as Gronk, Gronk just has a presence about him...the Pats' stats with and without him this season is mind-boggling...he makes great catches, he blocks insanely well which Graham can't do, and the defense has so many guys freaking covering him it often leaves another Pats receiver wide-open, the guy doesn't even need to do anything to be a huge impact. Graham is still awesome, though, I do love watching him make plays. But really, if Gronk stayed healthy all the time and say came around a few years earlier in '07...oh God I could hardly imagine the stats...
