I wouldn't say that trade worked out for Philadelphia. They got a decent return, yes, but they missed the playoffs in 7 of the 12 seasons since the trade and haven't made it past the 2nd round. They wasted the return by not addressing other areas. They probably would have been better off keeping Richards and Carter, who led them to the final two years earlier. That locker room crap sure worked out for us.
Personally, I don't see PLD fizzling out. He's too good. I like Vilardi a lot more than most, but the odds of him having a subpar season are much higher than PLD having one. Definitely a defining move, though. It has to work out for Blake to appear to have any semblance of success.
We all have our gripes with Blake, our coaches, and management in general. I think they get passes too often but I'm glad there is at least some accountability. I'd go nuts if it was like Wilson in SJ or Poile in Nashville, where it was just the same old stuff despite not getting a cup.
