I think ApatheticLeader is pretty right on most of this. Whilst Eubank did have a few really good performances, there were also fights which showed massive vulnerabilities. How many fights did he just not turn up in? I think we'd all agree too many, so I don't consider him to be the best non-heavyweight since Conteh. Focusing just on his good performances, you could make that case, but when you look at his entire career, there are too many mediocre showings from him. He was limited, no doubt.
Mike McCullum, Sumbu Kalambay, Ayub Kabule and Herol Graham were world class fighters. The rest of the British contingent, including Watson, were a level or two below.
Why would you look at his entire career when the question is quite clearly regarding the 1990-1991 middleweight version of Chris Eubank?
McCallum was an ATG who was above all of the fighters listed. Kalambay had ATG ability, but never managed to have an ATG career. Watson is right in the mix with the rest of the solidly world-class fighters like Kalule, Graham and Eubank.
Because it's too short a prime to look at. I'm not saying considering Eubank in his first three fights and then his last few when he was done, but you need to look at a longer period of his career than that. Calzaghe in 2005-6 had wins which were almost flawless but it's obviously too short a peak to look at and, to judge him as a fighter, you need to look beyond that to assess his skills properly.
You're right about McCullum being above the rest, and possibly about Kalambay. Eubank and Watson are very clearly a level below Graham and Kabule.
Graham was just elusive and unorthodox. He didn't have very good technique or power. Late in fights he'd look absolutely awful, but just be too awkward for his British/Commonwealth opponents. Kalambay and McCallum were streets ahead of him in terms of being skilled technical operators. Their fights were close, but Graham couldn't stand with a world-class two-eyed opponent and out-time and out-react him, and hurt him. He'd be on his bike or grabbing you and turning you, switching his stances, arm-punching from amateurish angles, etc. How can you say Watson wasn't on his level when he beat better ranked fighters than Graham (in Lee and Benn), dried up Kalule aside (which was about Herol's 40th fight anyway!). Eubank knocked Graham cold in sparring when he was 13-0, if he wasn't even on his level it wouldn't of happened.
Do you know his name isn't Kabule? You have said that twice now. How can you be so certain he is superior to Eubank and Watson when you don't even know the guy's real name? Bit difficult to paint it as a typo when it has happened twice. :think
You don't need to look at a longer time when the question refers to one version of a fighter. So you are incapable of having a discussion over whether the 1991 James Toney or the 1997 James Toney was a better fighter? :huh
Eubank fought a world championship fight every six weeks for five years, unheard of since Joe Louis. Joe Calzaghe by comparison fought once or twice a year for 10 years, so he was always fresh going into a fight. Eubank was always going to have occasional poor showings with his unique scheduling and frightening weight-loss techniques. If you took away 1/3 of his fights, say the poorer ones, would you rate him higher (consider his best performances came against Watson (1), Benn (1), Rocchi, Thornton etc anyway-the best fighters)? Calzaghe, for example, wasn't even fighting in the times Eubank was back in the ring.
Are you really going to include a sparring anecdote to show who is a superior fighter? Often performance in defeat show more than a victory.
I find it highly dubious that someone could watch and read enough about a fighter to have a very clear idea of his overall worth, but not pick up what his name actually is.
