Bob Williams

Caleb Williams and Bob Williams operate in completely different eras—literally decades apart. Bob threw for 981 yards across three Bears seasons in the early 1950s with a 55.8 rating, while Caleb's a modern franchise QB with exponentially more volume and efficiency. It's like comparing a Model T to a Tesla; both get you there, but the technology's transformed everything about quarterbacking.

Bob Williams never made Canton. His college résumé was stellar—1949 national champ at Notre Dame, consensus All-American, fifth in Heisman voting—but his pro career was brief and underwhelming. Sometimes the best college stories don't translate to Hall of Fame NFL careers, and that's his trajectory.

Williams' 55.8 passer rating would crater in today's pass-happy NFL. He completed 56% of passes at Notre Dame in 1949, which wouldn't cut it now. Modern rules, safety regulations, and defensive schemes would expose his limitations. That said, his arm strength and leadership might've developed differently with modern coaching and training—but honestly, he'd likely be a backup.

Jim McMahon laps Williams in every statistical category—45.04 rating versus Williams' 9.14. McMahon won a Super Bowl, threw for thousands of yards, and actually sustained an NFL career. Williams was a footnote; McMahon was a franchise pillar. Not even close.
