NFL executive vice president of football operations Troy Vincent says the league "failed miserably" in its introduction of pass interference replay reviews last season.

Vincent added that such failure would serve as a cautionary tale for the NFL to not rush rule changes in the future.

His comments came during a discussion of the "sky judge" proposal, the addition of a booth umpire to each officiating crew, a modified version of which is set to be voted on during Thursday's NFL owners videoconference meeting.

"We cannot fail this year," Vincent said. "We saw, a year ago, when [the pass interference rule] played out, starting with myself, what we put in place last year ... Those outcomes were not good for professional football. Because we didn't do the proper due diligence, it played out publicly. The last thing people should be talking about is the way the game is officiated. They [officials] should be faceless objects, managing and facilitating game flow.

"We failed. I'm first in line. I shared that [with league officials]. I failed as the leader of that department. I failed. We cannot allow that to happen again. What did we learn from that? We've got to do our due diligence. You can't rush and just shove something in there without knowing all the consequences. And we found that out last year, live and in action, publicly."
