The only one of BB's changes that was passed was the goalpost one.
- The "all plays reviewable" was outright rejected mad
- Extra point was tabled for a future vote, but with experimental implementation in the preseason
- Boundary camera proposal was tabled for a future vote.
The extra point rule, I'm sure they'd like to see how it plays in practice before seeing. On the boundary camera one, I'm sure the owners tabled it so they could get a cost analysis done before making a decision.
At least replay was expanded to include all loose ball plays as that makes logical sense, but to Belichick's point - that only creates more confusion on what's reviewable and not reviewable.
