I think Kawajiri is.
And Hansen next..
Hansen is overrated, i think Neer would beat him.
Kawajiri was a great win, but i think Alvarez matched up well with him, being the better striker. I thought neer would of gave Alvarez a bit of trouble on the ground, but he proved me totally wrong and ended up subbing him, thats why i was more impressed by that win.
Alvarez has really improved his ground game since his defeat to Aoki, winning 5 straight by submission.
