No he isn't. And as the article states (although not a Belichick quote), even though some plays are automatically reviewed, only the parts of the play that could be challenged normally can be reversed.
You don't seem to grasp the point Belichick is making.
Belichick is asking for
everything to be able to be challenged. Therefore, the concept of "only the parts of the play that could be challenged normally can be reversed" simply doesn't apply. You could challenge for holds, face masks, PIs, false starts, forward progress...
anything.
So you could easily have a situation where an interception is allowed to stand even though the defender clearly and indisputably commits pass interference (or a face mask or any of the other cannot-challenge aspects).
You're missing the entire point of the article.
"If it’s offensive holding, if you think one of the offensive linemen tackles your guy as he’s rushing the quarterback, and the ball hasn’t been thrown, they go back and look at it and if it’s that egregious of a violation they would make a call. If it wasn’t, they wouldn’t. We have to live with that anyway but now it’s only on certain plays and certain situations."Coaches only get 2 challenges (3 if both are right), so it seems unlikely that there would be any semblance of "fishing expedition".
As I just said, that does not apply to scoring plays, turnovers, or in the last 2 min of each half, where all reviews come from the booth (and there is no limit to them). Keep in mind that
coaches are not permitted to challenge in those situations. So what do you do if you're a coach and you think there's offensive holding on a scoring play?
The only answer is to review
every scoring play for any possible offensive hold (anywhere on the field),
every interception for any possible defensive hold (anywhere on the field),
every turnover on downs at the end of a half for any possible PI (anywhere on the field), etc. Either that, or you create a two-tier challenge system where judgment calls can only be challenged on non-scoring/turnover/end-of-half plays, which removes a lot of the point.
