Am I misunderstanding the term "deeper"? If one era has more active boxers than another era - does it not mean, that it has a deeper talent pool? You know as in "larger" or "bigger"? Or does "deeper" mean something else, that I'm not aware of (being from Denmark, English isn't my first language)?
It seems to me that PPV is becoming less of an influencing factor so that's a good thing. "Best" era is quite an absolute claim. I think it's a decent era with room for improvement thanks to more PED tests, less PPV influence.
Not the best era IMO, but definitely the best era ever to be a boxing fan. Abundance of rare films now, Internet knowledge, and message boards such as this one with dedicated fans and even historians. Awesome!
