Losses at the end of fighters careers that would undoubtably gone the other way

Just reading about tommy coyle and he seems like a good guy and is having a decent career but looking back through his record the fight against katsidis stands out

How would that one have panned out with katsidis in his prime?

Another example that stands out to me is Nigel Benn v Steve Collins

Thing with that one is tho, prime v prime I think Benn would have won but it would have been lot closer than coyle v katsidis, know what I mean?
