As in previous seasons, the NFL's replay review system reversed fewer than half of the calls it considered in 2015.
Coaches' challenges failed 54.2 percent of the time. Replay officials, meanwhile, upheld 60.7 percent of the calls for which they initiated reviews.
So it's no surprise that nearly two-thirds of NFL players polled by ESPN's NFL Nation said they would not want every play in the Super Bowl to be reviewable. In theory, expanding replay would minimize the chances of a bad call left standing in the most important game of the year. But in reality, players don't trust the system to provide better results.
Vice president of officiating Dean Blandino, a former director of the replay system, has instituted a high standard for overturning calls. As Blandino said in 2013, all calls are considered "correct unless we have indisputable visual evidence to the contrary." He added: "We are not going to try to re-officiate the play in the booth. We have a ruling on the field. If it's not clear and obvious that that ruling on the field is incorrect, the call will not be overturned."
There have been multiple proposals for expanding replay in recent years, all of which capped the number of coach challenges at two or three per game, depending on success rate. So the chances of substantively elongated games aren't high. More simply, players have seen enough seemingly inaccurate calls upheld by replay. They aren't at all convinced that more replays would be better.
Sometimes, perception is reality.
