Who threw the best straight right hand?

The straight right hand that won Joe Louis the heavyweight title of the world drove Jim Braddock’s gumshield through his top lip and opened a wound that would require twenty-three stitches. A crimson stain “a foot in diameter” spread across the canvas as the referee tolled off the ten. Louis had thrown a perfect punch by the highest of standards—his own. The killing field for Joe’s straight right is extremely narrow.

Finding comparable punching technicians is not easy but as an out-fighter, but Ricardo Lopez's perhaps comparable. Nothing like Joe’s equal as an infighter or short arm puncher, at distance he executes in combination as well as anyone and although he lacks the killing power of Joe’s straight right, I would consider him more flexible. He found ways to reach with the punch, to stab with it. He can be seen using it as a reverse jab. Most of all the width across which he is willing to throw it is much wider, his targeting for the punch is less impacted by tunnel vision. Louis has to bring his opponent into a very specific kill-zone to activate the trigger for that punch. He is arguably too much the perfectionist. He lets opponents get away—he let Billy Conn get away for a spell —because Conn could read and stay out of the narrow cone where the Louis straight gets lit up in.

For the knockout of Johnny Paycheck Louis used a covering jab and footwork to engineer an opening two inches across and then landed a technically flawless punch on that opening thereby creating a finisher which almost no fighter in any era would have survived. That is wonderful skill, and it must not be forgotten or minimized. But if there was a flaw in the punch it was the same flaw that would dog Louis for his entire career and beyond—that he was too specific. Whilst the beautiful improvisation of a left hook to Braddock’s biceps in order to facilitate a clear path for the narrow trench the straight right needed can dispel notions of stiffness in his boxing to a degree, Louis still needed a dirty counterpart to this precision punch. That was his right cross (by his own words), a dirtier punch, so a little lesson in holistic perspective because you could make the mistake of only thinking about Joes straight right in isolation and maybe find it a little wanting - but as part of an arsenal, he has the best ever straight right hand. Ha ha.
