Zolani Tete appears to have all the necessary hardware to evolve into a ring great
Retrospectively, it seems farcical that the reigning champion entered this first defence of his IBF Super Fly title as a 2-1 underdog.
English confidence centred on a September 2010 fifth round surrender to compatriot Moruti Mthalane in an IBF Flyweight spat when Tete was clearly weight drained.
The other two blotches on his 22 fight slate were 12 round decision losses - one majority, one split - in world title eliminators over in Mexico and Argentina.
In his two starts immediate to Butler, the man from Eastern Cape had iced ex-IBF king Juan Carlos Sanchez in Mexico, then executed a near shut-out over Japan's previously undefeated Teiru Kinoshita over in Kobe.
Five foot nine inches tall and blessed with a 72in wingspan, Tete is an absolute monster at 115lbs. Seventeen of his 20 victims have now failed to cross the finishing tape and on Friday we saw why.
The South African instantly dictated the pace, established his range then dismantled Butler for seven rounds until landing a perfect uppercut in the eighth to end the fight. Horrible viewing for the patriots, poetic for the purists.
Paul Butler needs to return to the drawing board
Team Butler entered adamant that their former IBF Bantam boss was one of the top 115lb fighters in the world, but Butler will now have to regroup and build himself back into world title contention.
'The Baby Faced Assassin' is highly skilled, teak-tough and ferociously competitive, yet it would be extremely difficult to construct an argument for him winning any of the seven completed rounds.
He started tentatively and thereafter struggled to build any momentum, perplexed by a left handed champion who enjoyed ridiculous physical advantages.
"Paul told me that the first jab to the body really hurt him and, after that, he thought too much rather than let his hands go instinctively. He just couldn't reach him," said coach 'Arnie' Farnell.
"He finds southpaws difficult and struggled in sparring, but you need to overcome these obstacles if you want to make history. He got beat by one of the best. No complaints.
"Paul's hero Marco Antonio Barrera got beaten twice by Junior Jones early in his career, once by knockout, and look what he achieved. After a good rest, we'll be back."
Jazza Dickens is a top talent but now needs to consolidate at domestic title level
The feted Scouse southpaw finally graduated to the vacant British Super-Bantam title with a clear and impressive 12 round points win over tungsten-tough tyke Josh Wale.
A former six-time national amateur champion, Dickens has copious skill and completed the 12 round championship course at a lively clip, having previously gassed out in round ten while ahead against Kid Galahad 18 months ago.
But impressive as he was, the 23-year-old still has scope to mature technically and mentally prior to being unleashed against the iron of the division such as Frampton, Quigg or Galahad again.
After a fractious weigh-in, at times he needlessly got dragged into a grappling match and, following deductions in rounds five and ten, was perilously close to being red carded for illicit use of the shoulder.
A maiden defence against Erith's WBA-rated Lewis Pettitt beckons, a fight that should satisfy the needs of both parties.
Jack Catterall is seriously good
Having bombed out top grade domestic starlets Nathan Brough and Thomas Stalker in the latter part of 2014, 'El Gato' set his mallet fists upon international competition.
Cesar David Inalef of Argentina had never previously been stopped in 23 (just four losses) but he was bullied from the off from the brutally strong 21-year-old Chorley southpaw. After being dumped in round two, Senor Cesar turned his back in round five.
Catterall entered this spat ranked 13th by the WBO and can now expect to advance a few more rungs. Don't be shocked if the ambitious Lancastrian bypasses the domestic scene and shoots for the major international belts.
He says, "only Bradley Saunders interests me. The British belt would be okay but my real dream is a world title."
Derry Mathews and Liam Smith are consummate professionals
Both had expected more taxing tests but capitalised on 'mark time' assignments by showcasing their considerable class before a hometown audience.
'Dirty Derry' masterfully negotiated a high risk job just six weeks out from his delayed WBA title challenge to Cuba's Richar Abril, by dominating then destroying Gyorgy Mizsei Jr.
The 21-year-old Hungarian had twice challenged for the European title and had survived the full trip against the likes of Thomas Stalker, Terry Flanagan and Anthony Crolla on these shores.
But Mathews wiped him out with a single raking right hand and his physical and mental well-being gave cause for optimism next month.
'Beefy' Smith is understandably vexed by the shortage of quality opposition prepared to face him. Nevertheless, the reigning British Light-Middle king was near punch-perfect in dismantling decent Polish middleweight Robert Taralek in eight.
He can expect a stiffer challenge when he returns to title duty on Mathews' undercard next month.
