I think the size of Baba is practically irrelevant here. The short stature of Taz actually works in his favor in this match because of his build and lower center of gravity. Taz not only knows Judo, but is a proficient mat wrestler as well. Take away the Taz-plexes and his arsenal is still well equipped. Giant Baba has lost to plenty men smaller than him and Taz would be no different. He would break Baba's legs down, grounding him and ultimately winning by Tazmission. I think Taz is just the all around better athlete and his superior athleticism would make all the difference.
