Look at what billy did differently in the last fight. It was his movement consistently for 12 rounds, didn't slow didn't take foot off. I think billy has always had the ability to do that but didn't have the engine to maintain it. Now with ingle he does, obviously they worked on technical stuff its elite level boxing. I'm just saying what he has got from ingle is his ck ditioning the missing piece of the jigsaw combine that with his already undoubted ability I think billy is one of the hardest fighters to beat out there
