Was Nicky Piper not intelligent in the ring just lacked ability? Clev has a 2-2 in a maths degree from a weak uni, he's no genius, that gets blown outta proportion a bit Tho to be intelligent in the ring u need to learn from ur mistakes and learn from difficult fights, Clev bought into his own hype after being fed taxi drivers for x amounts of defences.... We will see how intelligent in the ring more so after he comes back from that defeat
All the Klitchskos did to get a PhD was write a thesis about sports health or something like that. No doubt they smart tho. Gene Tunney hung out with many prominent writers of that time.
Still... Floyd Mayweather Jr. 50-0-0 Average IQ Abrasive ego Minimal education Unfavorable upbringing Swimming with most predatory people (boxing dimension). He managed to outdo any boxer both in legacy & materialistic gain...this basically the definition of Smartest
Ring IQ imo comes down to a few factors: experience, adaptability, ability to control the opponent, use of all aspects the ring (fighting off the ropes, feints dirty tactics ect). So the guys imo do these things best are: #1, Ezzard Charles #2 Willie Pep #3, Benny Leonard #4, Miguel Canto #5, Floyd Mayweather Jr HMs - Ray Leonard, Carlos Ortiz, Luis Rodriguez, Bernard Hopkins ect
