I think those rankings are pretty good, but RDA should be ahead of Conor.
Lol @ Conor still in the top 10. Hasn't won a fight @ LW in years, and is 1-2 lifetime in the division. Complete joke of a ranking.
pretty I think. Not sure that Chandler should be that high already. In mma you win some lose some. Chandler beat hooker, but that’s his only fight in the ufc. A 1st rnd TKO is also good, but at the same time you don’t get much to evaluate against other ufc level fighters
Meatgrinder - pretty I think. Not sure that Chandler should be that high already. In mma you win some lose some. Chandler beat hooker, but that's his only fight in the ufc. A 1st rnd TKO is also good, but at the same time you don't get much to evaluate against other ufc level fighters
Considering that beating Hooker in a close fought decision brought Porrier to the #1 contender spot, essentially, I think an emphatic finish merits being there.
At first I thought the Chandler ranking felt a bit high, because the guy he beat was ranked #6 and it was Chandler's only UFC fight.
But there's another pretty similar recent example: Jiri Prochazka.
Like Chandler, he came in with a big reputation from other promotions. His first fight was against Oezdemir, who is currently ranked #7. He finished him early in the 2nd round and he's now ranked #5, with a bout coming up against Reyes, who just fought for the title and is now #3.
There might be other examples, but I can't think of one off hand. (I don't think situations like Rousey's, where she was promoted to UFC champ after UFC bought Strikeforce, are similar.)
