“Shakur is levels above those fighters,” Crawford said. In Crawford’s view, Stevenson sits above Vasiliy Lomachenko, the southpaw who forced Lopez into his most demanding fight and pushed him through twelve hard rounds at championship pace. Lopez solved Lomachenko by controlling range early, limiting volume, and forcing the fight to be won in bursts rather than rhythm. That is the problem Lomachenko posed in reverse, and it is the problem Stevenson will be asked to solve. Saturday determines whether Stevenson has already reached the level Crawford is assigning to him, or whether that elevation still requires proof against the one benchmark that has held up.
