Tim Tebow and Colin Kaepernick were both out of football for extended periods of time, for different reasons, and each talked of how much they loved and missed the game. Both had opportunities to go to Canada—each was on the negotiation list of the Montreal Alouettes. Both declined. Plenty of other ex-NFL quarterbacks have walked away from the game, rather than try and pump life into the careers by working on their games in the relative anonymity of pro football’s de facto Triple-A league.
