OK, it is true that the referees won’t be calling as many penalties as in NFL. Also, the “out-of-bound catching” actually, is just college rules…One foot inbounds is a reception/interception.
Another rule change is that there will be no fair catches…which I think it a pretty silly rule, anyways. If you don’t want to get hit…get off the freakin’ field, you wuss!
Also, to make 4th down more exciting, any punt travelling more than 25 yards becomes a live ball, recoverable by either team.
There are no PAT kicks. To get your 1 PAT, you need to convert a TD from the 2-yard line. And if the defense returns a fumble/interception on the PAT, they get 1 point themselves.
There is no “In the grasp” rule for QB’s. He’s down when his forward progress is “halted”. But QB’s can still be protected, ref-wise, by sliding or otherwise giving up without taking too harsh a hit. Headslaps will still be illegal as in NFL.
Defensive backs are allowed the “bump-and-run” all the ay down the field.
Finally, the play clock will also change. 35 seconds when time is stopped, and 25 seconds when the clock is running.
So as you can see, ALL of these rules are either utilized by other leagues, or have been in the past. So, there aren’t any “invented” rules here…just modifications and combinations of rules to make for a more exciting faster-paced game!
