I think he still rethinks his game post-McCall and becomes more cautious. Pre-McCall he was good enough to destroy Rudduck and Bruno and beat Tucker and Mason. He'd still be favourate to beat McCall in the rematch and top Holyfield and Bowe and clean up the division.
I also think he still changes trainers. How about he goes to Brendan Ingle's Wincobank gym, that would be fun
