I realised I'd be pulled on that, but I think you can judge a change in size and speed in 2 minutes... not fully, but you can spot the difference to a degree. I've no scientific explanation but the guy was nearly 10% heavier than I'm used to seeing him, it was very noticeable to me, and he seemed slower as a result. As you'd expect I guess.
The Sun's saying 215, so apart from this we were all way off. No-one else had him under 220, most had closer to 230 (which I'd gone for).
as id said i heard an interview with adam booth where he'd stated that haye would have an extra lean stone ie.200lbs plus the extra stone.any more weight would have been unneccessary imo.
