I think it should be "Best of the Non-best". Well, I woukd just say "Second best" but each to their own.
That's not the same thing, though. The second best of an era could have possibly been number one at one point in the era. The best of the none best is the best fighter to never be known as the best.
None in this context doesn't make sense,did you mean NON? You always need to be specific with me because ; 1.I'm old. 2.I'm not very smart.
