What did we learn after Carl Frampton added a featherweight world title to his super-bantamweight supremacy in New York, while Josh Warrington continued his impressive ascent in Leeds?
Is Frampton the best domestic fighter?
Carl Frampton became a two-weight world champion by claiming the WBA featherweight title after stepping up divisions to challenge the previously unbeaten Leo Santa Cruz. Eerily, Frampton replicated his manager Barry McGuigan's greatest achievement by winning the same belt but Northern Ireland's latest boxing supremo may have out-done his predecessor.
In travelling to the United States to put his perfect record on the line, Frampton's win is among the greatest ever by travelling domestic boxers. Santa Cruz, the gritty Mexican had never fought in New York City and may have questioned what happened to his home advantage when he saw Frampton greeted by a raucous ovation.
In narrowly out-pointing Santa Cruz, Frampton's win counts alongside Tyson Fury's against Wladimir Klitschko in terms of modern-day boxers claiming world titles in foreign territory. Can any domestic fighter can now raise their hand and claim to be better than Frampton?
Just a few short months ago, it was questionable that he was even the best super-bantamweight on these shores. But he unified titles against Scott Quigg and made the gutsy call to step up for an even greater challenge. Ending the flawless records of Quigg and Santa Cruz consecutively (both in his opponent's preferred location in fights that were, beforehand, considered a coin toss) must put Frampton in a class of his own above any British world champions.
Is Warrington's power improving?
Hyland, in comparison, was bombed out inside just two rounds by Gary Russell Jr - the man who holds the WBC featherweight title that Warrington is now the mandatory challenger for. Such comparisons may be simplistic, but it identifies the sort of knockout ability that Warrington might require if he is to become a world champion.
The problem is not merely that every boxer would dream of a knockout shot like Anthony Joshua's. The concern for the Leeds featherweight is that the easiest fights of his career are already behind him and future opponents, aware of his light-handed notoriety, might opt to exchange punches believing they can absorb anything Warrington throws. If Warrington can't dissuade that tactic, his lack of fear factor may prohibit him from going all the way.
Is Stevenson doing enough?
Adonis Stevenson made the seventh successful defence of his WBC title on Friday night with a brilliant knockout, but he is in danger of becoming the odd-man-out at 175lbs.
Fellow light-heavyweight world champion Sergey Kovalev is about to engage in a mouth-watering bout against Andre Ward, a duel between two unbeaten fighters with the winner certain to claim they are the world's pound-for-pound king. Elsewhere, WBA champion Juergen Braehmer will finally give Nathan Cleverly a shot at the gold, in a fight that has been brewing for five years.
Stevenson, as a result, finds himself in the shadow of his peers. He demolished Thomas Williams Jr on Friday, hardly an opponent that stirs the kind of excitement generated by the upcoming two light-heavyweight world title fights. There is no questioning the Haitian's ability - he has a stellar record including wins over Tony Bellew, Andrez Fonfara and Sakio Bika within the past three years. But he hasn't ventured outside of his adopted Canada home in 13 fights and, now aged 38, time is running out for Stevenson to make a statement before he slips permanently behind the likes of Kovalev.
Campbell and Whyte on the comeback trail
First professional defeats in December for Luke Campbell and Dillian Whyte haven't dampened their growth, and they both recorded much-needed victories in Leeds on Saturday.
Olympic gold medal winner Campbell was handed a shock defeat by Yvan Mendy on the same night that Whyte was knocked out by Anthony Joshua, but both prospects have now recorded back-to-back wins since that humbling night at The O2.
Campbell, for his part, has eschewed previous habits and uprooted for Miami's warm-weather training and high-level sparring. He climbed off the canvas on Saturday to clearly out-point Argenis Mendez under the guidance of new coach Jorge Rubio, who he credits with his revitalisation.
Whyte, meanwhile, shed his reputation of being a hard-nosed brawler by demonstrating his technical side which Dave Allen couldn't compete with. The Londoner claimed afterwards he wanted to show his improved techniques, suggesting his demise at Joshua's hands was just a bump in the road of his career.
Welcome back Mikey
There was a welcome return for Mikey Garcia on Saturday night on Frampton's undercard, after a two-and-a-half year absence due to behind-the-scenes legal wrangling with his former promoter.
Such issues are an unpleasant slight on a sport that is difficult enough without having to read legal paperwork between sparring sessions. So Garcia's stoppage win against former WBC champion Elio Rojas was a feel-good moment - more so, his performance was slick enough to provide optimism that his time away from the ring may have re-lit a fire within.
