If Jon Jones became the greatest fighter of all time it wouldn't shock me. People need to hold off crowning him though. He's got a really tough road ahead of him in a sport that's unpredictable.
Personally I thought last year he was fighter of the year, most improved etc etc. However that being said he has a long list of opponents at 205 to beat before you could even think of placing him in the sort of category that GSP/Silva are in, in the sense that both have cleaned out their natural divisions.
Believe it or not, I personally don't think Jones has really been tested yet. His 2 biggest wins are arguably over Bader, who hadn't really beaten anyone of major note prior to fighting Jones other than maybe Little Nog who has done nothing in the UFC since his arrival. Then he beat Shogun who again despite being the champion I felt has been a overrated by the UFC.
Hear me out, his fights consist of a lose to Griffin, a win against Mark Coleman
(enough said), a win against the now retired Chuck Liddell who was never the same since Rampage KO'd him a few years prior, a lose to Machida
(fair enough I felt he was screwed but still) then a KO win over Machida. I mean with the exception of his 1 title defense against Machida I don't feel his performances have been that great. Hes 3-3 in the UFC with 2 of his wins over people who were over the hill & fought Jones after coming off another lengthy lay off..
Shogun was still a good opponent mind & more credible than Bader I feel, however I don't think beating Shogun means as much as some people do in regards to how he'd compare against the rest of the division or Anderson Silva.
