I get what you're saying. But having exactly 0 matches with leg passes and top/bottom makes Davis and Nagao a far better option for the time being. It's an interesting experiment taking a world champ FSer and putting him into a folkstyle D1 season (or 2)They could be thumb wrestling and Ono would still be a better option than Davis and Nagao
Personally, I think it's a bigger gap than people think. He's going to have a hard time unless he gets a lot of folk matches.
