Eubank was a good (if unorthodox) boxer with a good chin. These are the main weapons you need to beat someone like Barkley. I don't think Eubank would engage Barkely in a war - that would play too much to Barkley's strengths and Chris wasn't built that way. Middleweight or Super Middleweight- I don't think that makes a huge difference. There aren't loads of fighters I would pick Eubank over in that underrated era of the late 80s/early 90s middleweights but Barkely is one of them.
