Machida was landing that body kick when he wanted and was hurting Weidman (but didn't really seem to recognize it), Machida also goaded him into a brawl in rounds 4 and 5 where he did his best work and hurt Weidman quite a few times. Though Vitor didn't really land much due to Weidman covering up well, he did blitz Weidman and The Chris didn't really answer until the blitz was over, so that along with what Machida was able to do in the later rounds could indicate a measured in your face approach could be effective if it was done properly and his opponent both had the required speed and power and had the chin to take a hit or two. Weidman is very good at controlling distance and fighting counter strikers and strikers that try to sit back and use range, so it's difficult getting in on him, and rushing in is dangerous due to his power and ability to change levels.
Yoel has power, but I don't think he has the chin for it. Rockhold works best using his reach, his best shot would be to use body kicks, but he doesn't work best in close and the limited time on the feet against Machida wasn't encouraging. Jacare showed a good blitz against Mousasi, but similar to Yoel has been dropped and rocked quite a few times, and doens't work well enough in a ranged stand up battle. Mousasi would be interesting, but his wrestling isn't up to that level and could end up like he did against Jacare. Kennedy is too small. Brunson doesn't have the brawling ability. Machida is no longer the same. Vitor just had his chance and had nothing after the failed blitz. Prime Chael would have been interesting, but he kind of phoned it in a bit after the second Anderson fight. Bisping is past his prime (due in part to that eye thing), but wasn't enough of a threat on the feet anyway. Leites' strengths would be nullified. Anderson had two chances and in the first one his clowning permanently hurt his ability to take a punch. Gastelum is too small and doesn't have the high level experience. Henderson is too far past his prime and both too predictable and his takedown defense isn't good enough anyway (he was always susceptible to freestyle/folkstyle shots.
