This is quite possibly the most interesting match in the second round. Brother against brother.
For me, I think Terry Funk takes this in more ways than one. First let's discuss kayfabe. Dory Funk Jr. was tough, no doubt. He was one of the finest technicians pro wrestling has ever seen. Terry was no slouch in that department either. If this were, say an Iron Man Match, I might give the edge to Dory. But this is an ECW rules match, meaning anything goes, which clearly favors Terry. Dory wrestled some brawls and hardcore matches (mostly when he was teaming with Terry though), but Terry's second half of his career was defined by hardcore and death matches. Terry even wrestled in ECW and won the ECW title when he was 53 years old. The match rules clearly favor Terry, so in kayfabe, no matter how technical Dory is, how many moves he knows, he just wouldn't be able to overcome the toughness and hardcore experience of his brother Terry.
Now when it comes to who was the greatest wrestler and had more impact on the business and who was more all-around talented, to me Terry is also the superior Funk brother. Dory has the edge in technical prowess, and his reign as NWA Champion was longer. But when it comes to every other aspect of being a great pro wrestler, Terry has him beat. Terry was more well-rounded in style. He could chain wrestle, he could brawl, he could even do high flying moves late in his career. He could be an amazing heel or babyface. He was insane on the mic (far superior to Dory). Dory will be remembered as a great old-school NWA Champion who was a classic wrestler. While great, he certainly wasn't unique. Terry on the other hand was a pioneer of modern wrestling, he was more cutting edge, he was more fit for modern times, he was ahead of his time. And that's why his career was able to last much longer than Dory's was. Terry was wrestling in the mid 1960's all the way to the Monday Night Wars of the late 1990's. That's one helluva long career. And he was a big star through most of that time. And because of his diversity and longevity he was more important to the business than Dory was.
I could see people voting for Dory, but truthfully, I say voting for Terry Funk is the way to go here. Whether you're voting kayfabe, or on who was the greater professional wrestler.
