I thought it was a close fight and a fair decision. IMO aggression isn't meaningful unless you're controlling the space effectively, and I didn't see Akimoto really start taking control of the space and pace of the fight until round three. First round was clear for Wei, second round was much closer but I thought Wei landed more and still managed to control the fight more than Akimoto, round three was Akimoto for sure. I think Akimoto would have won in a five round fight. This fight kinda reminded me of Marat vs Superbon 3 in that the aggressive guy was missing a lot and the other guy was utilizing footwork to land pot shots and short combinations. If you rewatch the fight with a close eye, Akimoto's basically just shadowboxing for the first two rounds and occasionally catching Wei.
