1. Robert Horry
Drafted with the 11th pick in 1992, Robert Horry became an instant starter for the Rockets. Horry was consistently one of the Rockets' most reliable shooters in the early '90s, as his skillset was a perfect match for how Rudy Tomjanovich wanted to play.
The Rockets' strategy was to surround Hakeem Olajuwon, who was a great passer, with 3-point shooters. Olajuwon drew double-teams and kicked out to open shooters, like Horry.
But Horry had more to his game than just reliable shooting. The dude was perhaps one of the most clutch players in league history, and especially for a role player.
With 6.5 seconds left in Horry hit the game-winning shot in Game 1 of the 1995 Western Conference Finals, Horry drilled the game-winning shot. The crazy part is that Horry started the game 0-for-4.
Horry also drilled the game-clinching shot in Game 3 of the Rockets' NBA Finals matchup against the Orlando Magic with 14.1 ticks left in the game. During those Finals, Horry averaged 17.8 points, 10 rebounds, 2.3 blocks per game, and 37.9 percent from long-range.
Although Horry only played four seasons in Houston, it seems like he played longer than that, due to the clutch shots that he consistently made.
