What? You think you're cool just b/c you get well-lit stadiums and I'm shooting in the trenches at DII college sports? 
Just kidding!! Beautiful shots!
Come on, your photos are much better even if your stadium is contrasty or weak lit

I'm really amazed what 1dx and 300 2.8 or 70-200 2.8 II can do in good hands! Pretty impressive your work!
