Far too many variables here (i.e. season, indoors/outdoors, temperature, weather, venue, quantity to be consumed but I digress):
Augustiner (anything they make is good)
Brooklyn Brewery (Lager or Pennant '55)
Sierra Nevada Wet Hopped Ale
Shiner (Black, Bock, or Oktoberfest)
Rahr
Yuengling
Of course if its tailgating we're talking about then this is all out the window. Maybe 2-3 form this list, then on to Miller, Bud, or Coors Light ( I have no preference but usually rotate what I order every 6 months to keep things interesting) and then right before the game a good glass of 18 year Highland Park scotch on the rocks.
P.S. Don't forget the cigar while the charcoal is starting.
