However, it occurs to me that in about 20 years a good many alumni of this third-grade football mania  will be shocked to discover  that the world economy has too few insurance-selling jobs  to accommodate all the disappointed  young men who planned a lush  living in the NFL . The brighter among them would gladly trade a working knowledge of  Chinese or Arabic for all memories of  the ass-pats  they earned by not falling down too much.
If you can teach a kid the off-tackle slant when he's nine you can sure as Hell get him started  on something likely to be useful.  
Full disclosure: I personally played third-grade football if one of us could find the needle to blow up  David Stouffer's  leaky football and if the mean big kids weren't using the vacant lot and if it really seemed like more fun than walking down to the river  with a cane pole.  What a waste. If my community had had an organized youth football league and a few dozen daddies who were, themselves, frustrated  athletes, why, heck,  me and Joe Namath would have been team mates and drinking buddies. I guarantee it, and just writing about it deeply saddens me about my deprived childhood.
