Are you serious?
Aldo has much better striking than Frankie Edgar. Mark Hominick would absolutely tool Frankie Edgar standing, so I think that in itself speaks volumes for Jose's striking, especially when you consider he was ill for this fight and noticeably so.
The only thing I was unimpressed with from Aldo was his BJJ. I expected him to put a clinic on Hominick when it hit the mat, but he was unable to pass guard once.
How ever, Aldo still has vastly superior striking to Edgar and elite level take down defense and very explosive take downs of his own. He's got much more power in his strikes than edgar too.
His striking is his only A class attribute imo, his movement sucks, clinch can't recall seeing much of it but you can't just assume its going to be any good it an unknown, TD's are good, not world class but no a weak part of this skill set, Ground game ok could do with seeing more of it before casting real judgment but first impressions "what a let down".
You need more than just elite level striking to be considered P4P top level these days, and he has not proved that, I would compare him in many ways to Shogun but I think Shogun back in Pride was much superior on a P4P scale, I think you know how I rated Shogun now even after the victory over Machida, I think you know I never considered him the No.1 LHW and in fact believed he would fall short to a number of current top LWH's well on a P4P scale comparison right now thats how I rate Aldo against other P4P top rated fighters.
I have been borderline on him before, thinking we really need to see more of his skill set before we can make a credible shout for a P4P top class rating, but all we saw at UFC 129 was his elite striking only been fractionally above another top striker, when you think Silva you see striking miles ahead of other elite strikers hence why the P4P status swings in his favor, Aldo does not share than dominance, so unlike Silva his striking alone wont seal his top P4P status.
But still he has a level of striking that could put him in the P4P top list on a MMA scale if the rest of his game is equal to making him an elite all round fighter, and the other day he fell well short of showing that.
I believe Edgar is quicker, has better movement, better wrestling and could take Aldo down and smash him up to a decision or sub him. I think Penn is still P4P a better fighter than Aldo easily.
