Yahoo Sports reached out to all 30 teams seeking input from coaches on their feelings about the challenge through the first quarter of its inaugural season and the strategies they are using to maximize it during this trial campaign. Most declined to go on record, some of whom have publicly denounced it. One coach threw his endorsement behind the newly implemented tactic: NBA Coaches Association president Rick Carlisle. “I believe that any time you have a mechanism that could potentially correct an error in an NBA game that it’s a positive thing,” the Dallas Mavericks coach told Yahoo Sports. “I believe it protects the integrity of the competition, so I like the rule, and I believe as time goes on more and more people will feel the same way.”
