You can make $40m over a decent career as a kicker. You basically never take physical impact and as long as your legs work, you're good. No CTE or shit like that. Seems like a pretty decent deal even if you're talented enough to play a more glamorous position.
A few years after Martin Gramatica (probably spelled the last name wrong but you know who I mean) retired from the Bucs, he rented a tractor from the place I worked at because he was working construction. Just don't do whatever he did with his money and you'll be fine.
