This actually makes me wonder if the Donaire 1 long count (which even without my bias included, it was indeed long) KD was ruled a KO, how far Inoue would've gone. For reference, Inoue had 8 KO streak (every single one a world title match) prior to it stopping at Donaire 1. but as all knows currently an active 11-fight streak. If Donaire 1 was deemed a KO then he would currently be at 20-fight streak. Granted although I don't doubt that Inoue wins, this next fight against MJ I really won't be surprised if it lasts the distance simply given that MJ looks like the type that can withstand some damage. Ditto Ball if he still has a featherweight belt later next year. They got flaws in their games that makes it not too hard to win via points (which people sometimes forget but Inoue is really good at getting points too, and always leading by the time he KOs anyone regardless) but dropping/stopping them looks like it will be hard.
Honorable mention to gloved pioneer John Lawrence "The Boston Strong Boy" Sullivan - scoring 25 straight knockouts to start his MoQ run. (broken when George M. Robinson took a literal dive onto the canvas without a punch landing and was disqualified) Had the coward Robinson taken his lumps like a man, and factoring in Sullivan's subsequent stoppages before meeting Alf Greenfield, the streak would have hit 31. We unfortunately don't have complete data on his bareknuckle career - just three recorded bouts, but it could have been far more.
Akhmadaliev is a major hurdle, I agree. If he stops Akhmadaliev, then I'm not sure there's a super bantam that can last the distance with Inoue. His main enemies here are time and/or moving up to feather and beyond.
And while writing that out I realized that the result of the Inoue-MJ fight actually has more than I thought it did on it record book wise. If Inoue wins regardless of KO or decision: -Currently at number 5 with 25 *career* world title fight wins. Defeating MJ would put him tied with Joe Lewis and Mayweather for 3rd all time in world title fight wins after Julio Cesar Chavez (31) and Omar Narvaez (28). -Currently at number 3 with 25 *consecutive* world title fight wins behind Joe Lewis and Mayweather (tied for first with 26). Defeating MJ would put him in a three way tie for number one. -Currently tied with Canelo with a record 4th *consecutive* successful defense as an undisputed champion in the 4 belt era. Canelo's got cut by Berlanga when he was stripped, so with a win would become a single number 1 and could possibly go as high as 7 if he gets by MJ, Picasso, Nakatani before vacating and moving up to 126. -Assuming Canelo defeats Crawford as well it would keep the two tied at top for 5 career successful defense as an undisputed champion in 4 belt era. If Inoue wins with a KO: -Already owns the most KO wins in title fights with 23 (number 2 is Joe Lewis with 22 and number 3 is Julio Cesar Chavez with 21). Could increase to 24. with the next active -He can keep a 90%+ career KO rate (currently 27KO of 30 matches for 90%) and world title fight (currently 23KO of 25 wins for 92%). Would go down to 87.1% career and 88.5% world title match KO rate if MJ goes the distance.
One thing I know for certain that if Inoue "only" wins via easy wide UD without a droppage or KO, there's gonna be a loooooot of haters coming up with the "Inoue struggled again and is past his peak and will not make it at featherweight"-type of posts. Granted if he KO's MJ in an impressive way (which even as a fan of Inoue I doubt because MJ's durability seems quite high), the same people will say MJ was another overrated scrub and that Inoue is just scared of moving up to featherweight-blah blah so I guess not much of a difference?
You are correct! Had the Beast simply taken a year off in 1986, rather than getting stopped by Hagler & Duane Thomas - his original '80-'85 streak combined with his subsequent '88-'90 one up through losing to Norris would have been 36 straight kayos.
Anybody with under 32 is honorable mention at best...my OP listed the all-time historical top five and the current longest active streaks, neither of which he qualifies for. Also, screw Valero.
I think Artur Beterbiev should get a honorable mention with 20 KO’s in a row, majority of those was against live/world class opponents.
