FOX Sports Radio Weekend hosts Martin Weiss and Alex Monaco are in for Rob and Kelvin, and the guys tell us why it's so important for Shedeur Sanders to ball out in his preseason debut with the Cleveland Browns, explain why the NFL media at-large has been wrong forever about the importance of preseason football, discuss what we can expect from Justin Fields in his first season with the New York Jets, and tell us what they really think about Dabo Swinney's plan to go 16-0 at some point with Clemson.
