There doesn't seem to be any significant downside to extending the coaches' challenge to all football plays. As long as you limit it to 2 challenges - it will not extend the game from the current rules. I clearly think pass interference should be reviewable and challengeable. The argument against it is that that its a judgement call and this is a weak argument since so there are many other judgement calls that are currently reviewable (i.e., the spot of the ball) I can't understand what the resistance is in allowing all plays to be reviewable - especially in light of the support it seems to have from other football head coaches.
“I’m not proposing more challenges,” he said. “All I’m saying is, as a coach, if you want to challenge a play, I think you should be able to challenge it. And why does it have to be limited to, I don’t know, there’s four or five pages in the rules book of plays that can be challenged, and now this year there are more proposals to amend that probably because of one or two plays that happened in the league last year.
“I think eventually, each year, there’s gonna be some other circumstance, situation that comes up and we’re gonna want to add that. I mean it’s four to five pages of plays that challenge procedure. Every year it gets amended and it’s hard to keep it straight. I can’t get it right. We have a coach that’s responsible for that on gameday to know exactly … I don’t know how the fans could possibly get it right if the coaches can’t get it right. For the officials themselves, it’s challenging. I think it simplifies it. And I understand it’s a judgment call. So, if I throw a challenge on an offensive holding play and they look at it, and they don’t think it’s holding, I lose the challenge. But if it’s an egregious play, I don’t see why it should not be allowed to be challenged when it affects the outcome of the game. I think we can find multiple, multiple examples of plays for example where the offense isn’t set, that if the officials could look at it, it’s very clear that they’re not set, that would nullify what subsequently happened.
