But there's a wistfull and sad thing to a dude having to quit his whole life at age 30ish and find something new to do that has meaning and happiness behind it.
I think that's a good point, especially as a guy who makes it in the NFL has basically been groomed to do so since probably the age of six or something. All through every level of school, they are told that the only important thing is to get it done on the field of play, and it's a rare athlete at that level who really thinks about what else they're going to do, when they can't play sports anymore. (This is the same reduction of life to a single goal that results in so many college athletes doing whacked-out shit, like taking a crap in a student's laundry hamper, or ramming multiple cop cars with their vehicle . . . and former pro athletes doing the same sort of whacked-out shit like, oh, killing people.)
If you've ever seen Favre talk about his dad, it's instructive and a bit chilling. It clarifies why exactly he's got such an almost disturbing drive to succeed. If he was still playing with a talented team around him, they'd be doing much better. He's not the weakest part of the team, despite how much his abilities have slipped. But I think you're right, and he's not going to have as much of a fall-back plan as Tiki does, or Steve Largent, or the other exceptions to the rule. However, listening to him talk on Sundays and listening to his extended fan-club talk about him (Madden, Steve Young, et al), it's pretty clear that as soon as he hangs up the cleats he'll be in a booth.
