I was going to say that in that the second half of the 70s rides on the coattails of the first half a bit. But having made a bit of a chopper of myself in a debate about Chavez earlier this week, I thought I'd reread what I'd put (partly to check my grammar ) and I'm glad I did. Looking at some of the names on Ali's roster after Manila you see Richard Dunn, Jean-Pierre Coopman; Larry Holmes had a few stinkers too. So I thought it was a clear cut case of it being a decade of two halves. But then Ali also defended against Shavers, Norton and Young albeit he was a bit fortunate in the judging. Strong opposition. Holmes fought Norton and Shavers. The late 70s still had some good fights left in the tank. It had Foreman v Lyle, for one. And looking at the early 70s Joe Frazier defended against Terry Daniels and Ron Stander, Foreman vs Joe Roman so that mini era had a few stinkers too. As all eras do. The later 70s still had some good fights and though it was not as brilliant as the half a decade that preceded it, the gulf between the two halves was not as wide as I had initially thought.
