First, for the Cardinals, a really interesting (to me anyways) thing on 
NPR this morning about Larry Fitzgerald's vision.  His grandfather was an optometrist and when he was 8 or so, his grandfather would give him and other kids in Chicago vision strengthening exercises to help them do better in school.  The article credits his ridiculous ability to catch anything that remotely comes his way in part to his superior vision. 
Second, for Pittsburgh, a not too terrible song parody called 
Steeler Ladies (Put a Ring on It). (Spree: sound only, no video of Steeler fans strutting in leotards)
Finally, what do ya'll think of Troy Polamalu remaking the classic Mean Joe Green coke commercial?
