Joe Namath
Nobody wanted to see Namath play for the Rams after he left New York. He built up his reputation as one of the NFL’s most polarizing and popular quarterbacks. The Super Bowl winner was an icon in the Big Apple but he held on for too long and should have retired earlier.
He signed a contract in L.A. but this was a mistake because his body wasn’t the same. Injuries restricted him to a handful of appearances and he quit the sport after the season. It’s a pity that he didn’t retire after his final year with the Jets because they loved him (via N.Y. Daily News).
