Since I've been in a Madden CAG League (Madden 10) I've always been in the minority on the trading. I hate it when people blow up teams, a completely personal preference. I couldn't care less that BV has a "superstar" team, I just hate seeing Vick on the Cardinals/Roddy White on the Pats/Adrian Peterson traded etc.
The trade cap isn't my beef at all, I'm against unrealistic trades in general, cap or not. I was just as irritated by all the moves last year as well. If i had it my way, trading would be limited and "superstars" would be protected from trades in-season.
