It's not uncommon for promoters to support or hype their fighters and angle the narrative in their favor to make the fights more interesting, it’s part of the business. He can be a bit biased towards his fighters, but he does bring up some good points. The size difference is significant, and we haven't seen Crawford at 154 before. Madrimov's power is no joke either.
I do agree, but as boxing fans, we haven't heard of Madrimov, although as per Eddie Hearn he had a fight in Saudi and it's impressive. But common, if he is that hype we have heard his name at 154 lbs already. What size difference? Crawford might be walking around 154 lbs off season so there is no problem with the weight and the power here. You can said the same with Errol Spence power, it's no joke but Crawford knock him out.
Crawford's experience and technical skills are undeniable, but age and weight class can be factors. It'll be interesting to see how his speed and power translate at 154. He has consistently shown his skill and adaptability in the ring, but moving up in weight class always brings new challenges. Madrimov, being undefeated and holding the WBA title, is no pushover either.
For me that's not much any difference to be honest, As I have said, 154 lbs could be Crawford's comfortable weight, no need to drain himself to 147 lbs. While Madrimov still needs to go down to that weight and diet. But we will see, for sure though, Crawford will be the favorite even if he is the challenger here.
