In The Rainbow, our Fraternity magazine, there are generally two or three pages devoted to college and professional athletes.

I will just point out (again) that Delt claims three former SuperBowl MVP Quarterbacks:
John Elway, Denver Broncos
Jim Plunkett, Oakland Raiders
Mark Ripien, Washington Redskins (as usual, I'm sure I spelled his name incorrectly)
