I don't think Shogun is the same fighter he was in Pride, or ever will be.
He was renowned for his foot stomps, ground kicks and knees. That's a big loss to his repotoire.
He's beaten the likes of Overeem, twice, so his standup can't be too bad. But I haven't been impressed with him in his last three fights...how long does it take to get your act together.
He'll stick around in UFC though, good collateral for a Japanese show.
I'm going at a tangent now, but Akiyama v Wanderlei at middleweight would be huge main event if UFC ever headline in Japan.
