How the fuck has Vargas even been mentioned in this thread??

If fighters take some big shots then have to run a bit that's clever, they need to clear their heads before getting stuck back in.

Any fighter who goes down from massive shots do not have a glass chin and anyone who gets knocked out from big shots does not have a glass chin. Anyone can be knocked out if caught right.

Lewis had a good chin the 2 times he was knocked out those shots would have sparked anyone.

A glass chin to me means a fighter who goes down from a punch that he should be able to take and isn't particularly hard. If he gets up then sweet try not to get caught again lol
