First of all, you Broncos Fans know nothing about the weather in the south. Having lived in the humid gulf coast is so much worse than when I lived in Texas. not even close. DOn't get me wrong, the weather in Texas sucks, but it's not as bad as the gulf coast. And having been to Miami, the gulf coast weather isn't as bad as Miami. IF A>B>C, then Miami is WAY worse than Texas.
Given that, to address ScrepsMJ's quote. WHen I lived in Indianapolis and colts were coming down to Miami in September (Approx 8-9? years ago?)> I watched that ******* harbaugh on the TV interview say "We have bad humidity in Indianapolis, we train in it, we're professionals, we will not have any problems in Miami". Well, guess what, Little Jimmy had to pull himself out of the game in the 4th quarter due to heat exhaustion. So, it does make a difference. Maybe not to Tampa, JAX, NO teams, or to every player, but to everyone else, it does.
