Okay. Now it begins to make sense.
I didn't know the AAFC and the NFL had different numbering systems. That explains why Otto Graham went from a funny looking #60 as quarterback to a more "normal" #14.
Slightly off-Condi question: To which league did the Cleveland Rams belong?

The Cleveland Rams were the 1945 NFL champs and then they moved to L.A. for the '46 season. And then, one of the last perfect things to happen in Cleveland sports: the Browns joined the NFL in '50 and beat the Rams on Christmas Day for the championship that same year. It just can't get much better than that! (although '64 came close)
