What position would he play? I guess he has to be the quarterback -- who would want to be giving Jebus orders?
Point of fact, tho, the Judeao-Christian tradition doesn't have much in the way of an athletic underpinning. That's much more a product of the (pagan) Greco-Roman tradition. Numerous Greek myths involved contests and races. Well, we know that as the mental virus known as christianity spread, it wasn't shy about "borrowing" from other religions -- the christmas tree for instance.
Speaking of which, one of my brothers' family has been having their late december holiday observance, with a celebratory dinner and exchange of gifts, on the date of the Winter Solstice, rather than December 25. I think it's a great idea, my kids like it too, probably be more problematic getting buy-in from the wife. Still, the solstice is definitely something to celebrate (the days are getting longer! The days are getting longer!). And this past year I found it natural to dispense with "merry xmas" and to say "happy solstice" in addition "happy holidays".
