Free agent quarterback Tim Tebow wouldn't succeed in the Canadian Football League because of a weak throwing arm, Hall of Famer Warren Moon told radio station KILT-AM in Houston.
"You have to be able to throw the ball up there, if anything," Moon said. "They throw the ball a lot. It's only three downs, so the passing game is much more important up there, and there's a lot more field to cover.
"If you can't throw the football, it doesn't matter where you play quarterback. You have to be able to throw it."
Tebow was released Monday by the New York Jets. The Montreal Alouettes own his CFL rights and would sign him, assuming he's willing to compete for the backup job.
