Maybe to you it's just entertainment. To some people, they take it very seriously, and it's a huge part of their lives. And if you want to compare Tom Brady to a lead singer in a crap ass band replacing its crap ass singer, you just don't have a clue about football.
BTW, your analogy is faulty. What would the Rolling Stones be without Mick Jagger?
Your oversimplification of what will make this a good team, i.e., Mallett becomes SB MVP by virtue of trading Brady and getting a "good" defense is ridiculous, immature, and not worthy of posting.
