At the risk of sounding like a homer, you nailed it! In fact, I could never understand anyone calling the Patriots arrogant. In all my years following sports, I have never seen a team that falls over backwards to compliment their opponent like this one. They could be playing the '08 Lions, and the Belichick and Brady soundbites would make you think they were playing the '84 49ers. Contrast that to the 2001 Steelers, whose coach (Cowher) and QB (Kordell Stewart) were quoted to having their itinerary in New Orleans all plotted out for Super Bowl week, BEFORE they played the AFCCG. If the Patriots ever did that, we'd never hear the end of it.
Also, Brady has NEVER thrown a teammate under the bus after a tough loss. If anything, he always blames himself, and more times than not he's carried the team. Contrast that to a certain QB that has thrown his offensive line and "idiot" kicker under the bus after tough playoff losses.
