Former world champion Kell Brook has issued a firm and experienced warning to Terence “Bud” Crawford as the pound-for-pound star edges closer to a potential super-fight with Canelo Alvarez. And Brook speaks from a place few can:
he’s faced both elite-level technical boxers and punishing power punchers — including a terrifying step-up in weight when he fought Gennady Golovkin.

In an interview with boxing media, Brook didn’t mince words:

“I knew when I boxed Golovkin that I was stepping into something totally different. It wasn’t just about skill — it was the strength, the size, the power. And Crawford’s going to feel that exact same thing if he steps in with Canelo.”

 A Lesson in Weight Classes

Brook famously moved up two full weight divisions to face Gennady “GGG” Golovkin in 2016 — a fight he ultimately lost via TKO after suffering a fractured eye socket. It was a brutal lesson in the dangers of crossing into territory where physical advantages matter just as much as skill.
