I really wish he'd start incorporating more grappling into his repertoire, he's got the build for it. Balance is his biggest issue, sometimes it's like he has banana-peel shoes on, but he seems to fare better when he can get a hold of his opponent.
I've always seen him as the darkhorse when compared to other similar rikishi like Hoshoryu or WTK. He's rough around the edges, but with a bit of polishing, I could see him going on his own Yusho run one day.
