This is a good step up for Russell but one where I think he’ll struggle. Payano is a proven world level fighter who arguably beat Danny Roman in his last fight while Russell has fought no one of note and hasn’t been that impressive in doing so. While Russell is clearly skilled I think this is to much of a step up for him and that Payano will outbox him using his experience. He’s also a world class southpaw which will be even more frustrating for Russell to face.
I think Payano will be too experienced for Russell who hasn’t faced any real competition yet in his career.
