James Lileks,no fan of fishing or baseball, has an er....interesting idea.
If they could combine fishing and baseball, we'd have twice as much action. "And it's a line-drive cast up the middle -- Johnson throws it right at a muskie! He's hooked! -- but no! The umpire is signaling Johnson was over his limit, so they're throwing it back. That's two outs and one DNR fine." But even that would wear thin after a few innings.
A commenter had a fine take on an old saying.
Give a man a fish, and you'll feed him for a day. Teach a man to fish, and he'll sit in a boat and drink beer all day.
