When you look at Liger's runs, the fact that he's held every major light heavyweight championship in pro wrestling, it's extremely impressive. However, when you look a little deeper, it's not quite as impressive, at least to me.
Liger is probably best known for his runs as IWGP Junior Heavyweight Champion, which he's been 11 times in his career.
Reign 1: 77 days - 3 title matches
Reign 2: 200 days - 2 title matches
Reign 3: 165 days - 3 title matches
Reign 4: 58 days - 1 title match
Reign 5: 139 days - 4 title matches
Reign 6: 628 days - 6 title matches
Reign 7: 116 days - 3 title matches
Reign 8: 183 days: 5 title matches
Reign 9: 403 days: 9 title matches
Reign 10: 49 days: 2 title matches
Reign 11: 227 days: 4 title matches
So while Liger was IWGP Junior Heavyweight Champion for a total of 2,245 days, he only defended the title a grand total of 42 times. For a few of his reigns, he had title matches consistent with the frequency of champions in major American companies like TNA and WWE. It's easier to have massive runs with a title when the champion doesn't wrestle matches for the championship very often. That's a point that CM Punk brought up at one point during his WWE Championship reign comparing himself to Bruno Sammartino. It pissed Billy Graham off so much that he wants out of the HOF.
What's the point? I guess the point, at least for me, is that while Liger is a great wrestler, something that can't be denied. However, it also, again to me, makes all the various "wrestling god" or "he's a god in Japan" arguments I've seen towards Liger in past debates in these tournaments carry much less weight.
I'm actually a little surprised to see that this match is so close. Every year, people jizz themselves over Japanese & Mexican wrestlers and flip out when they don't flat out dominate whomever they're put against.
I'm going with Sid here because, as others have pointed out, Liger is a junior heavyweight. Possibly the greatest junior heavyweight of all time, but a junior heavyweight just the same. Maybe it's just the American mentality but when I think of wrestlers who have to compete against wrestlers who are of similar size, it gives the impression that the company believes smaller men are inferior to big men. It's not true in actuality, but that's the impression I get in Mexican & Japanese promotions who regulate wrestlers to certain weight classes.
It's not going to bother me if Liger goes over Sid here. I get that the guy's great and liking someone more than someone else is reason enough for people to vote Liger over Sid. Can't blame 'em. I myself was never a big fan of Sid. He was an imposing, impressive specimen, but he'll never be thought of as one of the all time greats despite being a 4 time World Champion, albeit for a combined total of 97 days. I think Liger could beat Sid, I just think it's unlikely outside of Japan or Mexico.
