With the start of a new NFL season just days away (that's right, the first preseason game is Thursday night), it appears, based on reports, that both players and officials are more confused than ever with the league's new rules regarding helmet to helmet contact.

From espn.com:

A presentation this week by NFL referees to the Philadelphia Eagles on the new helmet rule caused frustration among the players, according to team members, and created further confusion for some about what is expected of them.

And the sports network explains why uncertainty reigns:

Under the new rule, a player will be penalized 15 yards and potentially fined or ejected for lowering his head to initiate and make contact with his helmet against an opponent. The rule applies to not only tacklers but linemen and ball carriers as well.

101.7 / 710 KEEL's Robert J Wright and Matt Parker discuss the new - and vague - rules, specifically how it will change the game, rendering the days of battering ram running backs like Earl Campbell, walter Peyton and LSU great Jim Taylor things of the past.
