"When someone moves against Canelo we know he has problems. He doesn't fight good against movers. We saw that in the fight against Lara and Floyd Mayweather. With this fight he is fighting a guy who has a similar style to Lara and Mayweather. I move quick. I have good feet. I got power. By moving up to 155 I really believe I have a lot of punching power at that weight. I am not going to rely on that. I have to use my speed," said Khan. from b. scene I fear for Canelo's mandible. Khan is too dangerous with his new Goku power.
Canelo has nowhere to hide. Khan is coming for him. ...But..could it be a case of Khan acknowleding his increase in power (which is what happens when you increase strength and muscle mass)...but the overall increase in power may not be so significant given the fact he's fighting a MW.
His power will increase because he's bigger, but the bigger guys like Canelo absorb shots much better so his relative power may decrease and probably will decrease.
