WATCH: Rockets bench laughs at OKC's Andre Roberson for free throw struggles

Andre Roberson has been great in the series, but he was bad from the free throw line

Game 4 between the Oklahoma City Thunder and Houston Rockets on Sunday might boast one of the most unwatchable sequences in NBA playoffs history. There were many things that went awry for both teams, but among the most unwatchable events was the Rockets' decision to play hack-a-Shaq with Andre Roberson, who shot just 42.3 percent from the line this season.

Houston targeted Roberson as the Rockets played from behind, and Roberson simply couldn't buy a free throw. He went 2-for-12 from the line, which had the Rockets bench busting up with laughter.

Thunder coach Billy Donovan was in a precarious position with Roberson, who is without question the team's best defender. It's important to keep Roberson on the floor because he's assigned to defend James Harden, but his misses at the line essentially shot the Thunder out of the game. One has to wonder if Donovan made the right choice in leaving him in.

The late-game free throw collapse for Roberson overshadowed what was otherwise a solid game. He finished 5-of-9 from the floor and recorded 13 points -- his fourth consecutive double-digit scoring game this series, despite averaging just 6.6 points per game in the regular season.
