By Scott Gilfoid: Amir Khan says he thinks IBF welterweight champion Kell “Special K” Brook is wasting his career by failing to take on the big names in the sport, and he thinks the soon to be 30-year-old Brook needs to step it up and start facing the best. However, Khan suspects that Brook will vacate his IBF 147lb title rather than facing unbeaten Errol Spence Jr. (20-0, 17 KOs), who is one step away from becoming Brook’s new IBF mandatory challenger.
Khan calls Brook “Mr. Mandatory” due to him having already fought two mandatory challengers in his two years as the IBF welterweight champion. But Khan thinks that Brook will choose not to fight his next mandatory if it winds up being the 26-year-old Spence.
By Gav Duthie: After dispatching of two mandatories in the last year (Jo Jo Dan, Bizier) that Kell Brook could have beaten on the same night he now has a real live danger in front of him with newly instated mandatory challenger Errol Spence Jnr 20-0 (17). 
By Scott Gilfoid: Well, you knew it was too good to be true. Instead of undefeated Errol Spence Jr. (20-0, 17 KOs) being he mandatory challenger for IBF welterweight champion Kell Brook (36-0, 25 KOs) straightaway, the International Boxing Federation is requiring that Spence face #3 IBF Konstantin Ponomarev (30-0, 13 KOs) in an official IBF eliminator before he can become Brook’s mandatory. In other words, it wasn’t enough that Spence beat the highly accomplished Chris Algieri last Saturday night. 
By Scott Gilfoid: IBF welterweight champion Kell Brook (36-0, 25 KOs) has had things pretty easy during his long 12-year pro career in the sport. 
By Scott Gilfoid: Amir Khan isn’t worried about IBF welterweight champion Kell Brook right now. He’s got bigger fish to fry against the tank-like WBC middleweight champion Saul “Canelo” Alvarez, who Khan faces next month in less than 30 days on May 7 on HBO PPV. 
By Scott Gilfoid: Errol Spence (20-0, 17 KOs) showed last night why people are picking him out to be Floyd Mayweather Jr’s replacement as the biggest star in the sport. Spence completely crushed Chris Algieri (21-3, 8 KOs) in knocking him around the ring like a rag doll before putting him out of his misery in the 5th round with a perfectly placed left hook to the head that left Algieri on the canvas in a pile of bruised flesh. 
By Gav Duthie: There was quite an interesting night of boxing on Saturday night with action in the UK and US. Its been a relatively quiet March and although my interest was registered last night all of the fights were predictable in their outcomes. The question is what next for these talents. 
By Scott Gilfoid: IBF welterweight champion Kell Brook (36-0, 25 KOs) says he should retire if he can’t get a big fight in the summer against one of the big names in the sport. Brook beat his #1 IBF mandatory challenger Kevin Bizier (25-3, 17 KOs) by a 2nd round knockout last Saturday night at the Sheffield Arena in Sheffield, UK.
