I see where your coming from, but when looking at the streak Anjos was on before he lost to Eddie and the streak Ferguson is on, it's not even close. First off, about the Tibau thing, I did think he was cut but your correct he is only serving a suspension until Feb. 2018. But let's be honest, Tibau isn't no contender and has been around for ages, so once again I don't think that win is super impressive.
Compare Anjos streak prior to his last loss to Ferguson streak, it's not even close!
Anjos wrecked 1 former champ during that stretch, the only guy to stop Henderson by TKO/KO. He destroyed Nate, who is always game. Actually Nate would beat Ferguson IMO. He destroyed Pettis when Pettis looked unstoppable and was at the top of his game. Made quick work of Cerrone who is destroying people at WW now. Not to mention he beat Cerrone already before his lost to Khabib. He was never in any danger in any of those fights during his streak, yet Ferguson was getting tagged easily by Barbosa and rocked my Lando. That's finishing Bendo by TKO, Diaz DEC, Pettis DEC, Cerrone in the 1st not to mention finishing Jason High, pretty impressive stuff.
Now I will say the post RDA USADA is what scares me the most, because there is a good chance that stretch was due to that since he was looking noticeably bigger since the Henderson fight.
When comparing the two streaks, Ferguson's doesn't look impressive at all to me, but again that's just my opinion. I think it's more of Rogan hyping up Ferguson and etc. that has people so high on him. Ferguson's streak reminds me of the streak Matt Brown was on. Relentless forward pressure style and etc works on lesser opponents but when the competition gets better, that style will be less effective IMO. 3 things I give Ferguson credit for is his aggressive pressure, heart and D'arce choke. That D'arce is really effective for him because even though he might not get it, it can put him in a great position on the ground once someone defends it.
I would not be surprised if Ferguson wins but I like Anjos here.
