This makes me laugh incredibly hard. Apparently you missed the Patriots game huh? Had that been a 1 PM kickoff, how many more Dolphins would have left the field with cramping issues. The "advantage" is a misnomer. It is only an advantage if your team is in superior shape. Also, read Dave's post about his stadium experience.
I'm sure he knows that with all things being equal, the heat is definately an advantage. Obviously if the Dolphins are out of shape and can't take it, then there is no advantage. No need to belittle his argument when the response to yours is "duh".
