Howe well do you think a prime Too Sharp Johnson would do against the current crop of fighters 115 - 118 lbs? You have Sor Rungvisai, Estrada, Inoue, Tete, Burnett, Nietes, etc. I'd say he'd beat everyone. Too Sharp Johnson at his best was one of the most well rounded and skilled fighters at the lower weight class. He was like Sweet Pea Whitaker with a punch and more offensive minded (although more flat footed and not as good defensively) and a better version of Terrence Crawford. The only guys I see having a chance against him would be Inoue and probably Sor Rungvisai.
Hed be too sharp for most I'd wager, but Wangek could be a "will over skill" type of deal and Inoue would be superior talent beating out superior craft.
You'd have a better chance posting this in classic, there's actually been some recent talk of "Too Sharp" over there.
