Story:They played the Grey Cup on Sunday in Vancouver, but the C.F.L. battle that many people wanted to discuss happened at the Canadian Football League alumni luncheon two days earlier. Joe Kapp, 73, fought an old C.F.L. adversary, Angelo Mosca, also 73, on the stage.Andrew Bucholtz of the 55YardLine blog, which covers the C.F.L., has the details and asks: “Is it really worth it for them to engage in such a serious fight over something that happened in a single game 48 years ago?”Drew Edwards of The Scratching Post blog, which covers the Hamilton Tiger-Cats, gave the background: The animosity between the two dates back to the 1963 Grey Cup game, when Mosca hit running back Willie Fleming with a shot that many – including Kapp – felt was dirty. It knocked Fleming from the game, which the Ticats won 21-10. Kapp refused to shake Mosca’s hand afterward.Mosca said Kapp started things on Friday by swearing at him after he tried to say hello. Mosca was also quoted by Edwards as saying: “They showed the Willie Fleming incident on the screen – it was like it was a setup. He comes up to me with a flower in his hand taken from the table, one of the centrepieces, and he sticks the flower in my nose.Then he shoves it in my nose. I reacted with my cane and then he punched me and I went down. Then he kicked me.”Kapp, the only person to play quarterback in the Super Bowl, the Rose Bowl and the Grey Cup, was later a head coach at Cal, most memorably when the Bears beat rival Stanford on a madcap series of laterals that culminated with a touchdown amid celebrating Stanford band members. Kapp said, “The Bear will not quit, the Bear will not die.” Apparently, the Bear does not forget either.
