Misprint in rule book???

[ljudge]

Has anyone noticed the change in rule 5.1.2b? There was nothing mentioned in the front of the book with the other changes. It used to say "After a fourth down, a new series of downs shall be awarded only after considering the effect of any act during the down, other than a nonplayer or unsportsmanlike foul."

In 2004 it says..."After a fourth down, a new series of downs shall be awarded only after considering the effect of any act during the down."

This has to be a misprint. This would mean that all live-ball nonplayer and USC calls could put the ball beyond the LTG AND have A remain with the ball for a first down. The case book however 5.1.2(situation e and comment) - page 38 has the ruling that is consistent with the old wording.

I happened to stumble upon this because I'm looking for the rule that supported the following situation.....

I believe that if an B player enters during a 4th down play and doesn't affect the play AND team A falls 2 yards short of the LTG, then I believe B still gets the ball after penalizing the 5-yard nonplayer illegal sub foul from the succeding spot (vs. giving A a first down).
