People are not giving Horry enough credit for how well he played last year in the playoffs. Against Denver, Horry was huge. Behind Duncan and Parker, Horry might have been the third best player on the team in that series. He hit timely shots and had a couple key defensive plays. If he didn't have that block on Iverson in Game 2, the Spurs might have actually been eliminated in the first round.
Against the Suns in Game 1, he was also very good. In what may have turned out to be the most important game in the series (and, really, the playoffs), the Spurs don't win that game without Horry playing as well as he did.
Sure, after Horry got suspended, his play suffered. But by then, the Spurs had already moved past their toughest opponent of the playoffs and faced two teams (Jazz and Cavs) that Horry didn't matchup well against. Both of those teams are physical, rebounding teams, which was a much better matchup for Oberto.
For some reason, Spurs fans only remember Horry hitting that shot in '05. They don't remember any of his other big games from that year. And now Spurs fans are acting like Horry didn't do anything last year in the playoffs when he was brilliant against the Nuggets and very good against the Suns in perhaps the biggest game of the series. Without those performances, it'd be easy to imagine the Spurs not winning the championship.
