I could go along with that if the number is very limited. I've heard that penalties could be called on just about every play.
While we're on the subject: are teams still allowed only two challenges per game?
I thought it was two per half.
And is a team charged with a challenge EVEN IF they're correct? If so, that's wrong.
They are, but they're not charged a timeout. I don't have a problem with that. I've yet to see a case where a team ran out of challenges.
That is correct - offensive holding could be called on every play. Offensive lineman get a feel for the how tightly the officials are calling the game and adjust their play accordingly.
Illegal contact downfield could be called against the secondary on almost every play too.
I would like the see the standard of pass interference raised - that would result in less judgment calls that could really go either way.
