Aldo's boxing has looked very impressive lately. He's had to use it as his primary weapon in his last two fights due to his kicks being negated, but from what I've seen he's a definite top boxer in the UFC.
Condit's boxing also on point against Kampmann.
I missed Nurmagomedov's last fight but I'm going to watch it when it re-airs tonight. I love that kid, I see him being a huge factor in popularizing grappling even further when it comes to casual fans.
