Media day typically ends with the league coaches being briefed on officiating rules changes for the coming season.
This season brings several significant ones.
One of the most notable will bring the NCAA game into line with the NFL, as there will be 40 seconds between plays in most cases.
College football also is altering several rules to emphasize player safety.
A particular area of emphasis is player safety. New rules will penalize tacklers for hitting with the crown of their helmet or targeting defenseless players with hits above the shoulders. There also are new rules regarding horse-collar tackles and simplifying the rulings on chop blocks. This season all facemask penalties will be 15 yards, however, incidental contact won't be called.
Also this year there will be no warning for sideline infractions – players or coaches wandering too close to the field. This season it will be a straight 5-yard delay-of-game penalty for the first and second calls, and a 15-yard unsportsmanlike conduct penalty thereafter. (However, three sideline calls in the same game is rare to the point of unheard of in the Pac-10.)
The illegal-forward-pass rule was tweaked so that now the thrower's entire body must be across the line of scrimmage for the infraction to be called.
And this season the game officials have the general power to use replay to overturn "egregious" officiating errors. This won't allow they to overturn foul calls such as pass interference, etc., but can be used for cases where a fair catch signal is missed, the clock runs when it isn't supposed to, or if there is question of whether a field goal attempt did or didn't go over the crossbar or between the uprights.
Finally, there has been a tweak to that frustrating call that disallows fumble recoveries simply because the official blows his whistle. Now, if the replay shows that the fumble lost control of the ball before being officially down, the recovering team will take possession as long as the whistle doesn't obviously cause players to pull up.
