Fitz seems like a good guy. I really wanted the Cards to win that Super Bowl a few years back, for his sake as well as not wanting the Stealers to get another ring.
I suspect what he is trying to state is Seattle has his favorite home crowd. If anyone has gone to game in Glendale it's easy to see why , that stadium is silent compared to Seattle
Having a "that guy's girlfriend is way more into me than him" style fantasy is great and all but I think he's just saying he likes the energy here because he likes the energy here...
