In terms of size. Not star power.
Besides, Andre The Giant had both. Probably the most recognizable face in all of WWWF/WWF/WWE history.
Anyways, this is primarily for the big athletes in WWE. Like Andre The Giant, The Big Show, and Giant Gonzales.
I always liked GG's character, but gawd...he was such a horrible wrestler. Allegedly 8' tall(actually 7'4", NOT 7'6" like some would want you to believe), he was the tallest WWE wrestler(ATG was around 7'2" as I recall, not 7'4" or 7'5").
It's amazing seeing the match between the Undertaker and Giant Gonzales. The UT is around 6'7"(no way he's 6'10", not when 6'5" The Rock can almost look him eye to eye) and seeing him next to GG was like...woah.
TBS should be a little more athletic. I hope he continues to use that torpedo he used against Orlando Jordan a few weeks back. But he's probably not big enough to really be remembered like ATG or GG down the line, despite having the WWE title more than GG ever did. I think TBS is more like 6'11" or even 6'10", I think he said that on Conan O'Brien's show or something...no way he's 7'2". But eh.
