Shakur Stevenson has weighed in on the perennial boxing argument: Terence Crawford versus a prime Floyd Mayweather. The question circulates again because Crawford remains undefeated at the top of the sport, and the sport has no clean mechanism for settling hypotheticals about fighters separated by era.

Stevenson’s position is notable because he has trained alongside both men and occupies the rare vantage point of someone who has shared a gym with Mayweather and studied Crawford’s career in real time. His verdict, whatever its precise content, carries the weight of proximity rather than pure speculation.
