I agree that it seems less... pure somehow, picking up vets at the deadline, but that is the way the game is played these days. I was thrilled when we got Sam last year (I was at Florida State with him), and even though he didn't fit in the way I hoped he would (bad shots, too many shots, etc), I always feel that the locker room leadership of winners like that is a key intangible. If Horry was on board, he'd certainly help the team in small ways.
Having said that, I don't know that Horry is the perfect fit for this team, especially if all he's got left in the tank these days is the three. PJ Brown is better for the Cs.
But I do disagree about Horry's clutchness. Much like Cassell, he had his biggest games throughout his career when his team most needed him to step up. That's clutch, and it's more than his game-winning threes. How about that cruise-the-lane dunk he had on Phoenix 2 years ago?
But I also think Horry has a bad temper, which would explain the Ainge towel incident and the hip-check foul on Nash. Might be a side effect of all that pressure, who knows.
