Last week vs Dallas, Casey was flagged for being downfield too far on a passing play...

2 questions:

1) What is the rule exactly?
2) Why is that rule in place? My brother and I have two theories (one is about blocking and the other is about appearing like an eligible receiver)

After the game, Trevor M on CSN said that a OL can block a guy all the way down the field on any play, as long as he's engaged with the defender, once he's not engaged he needs to drop to a knee to avoid the flag on a passing play. Does it matter if you're in the play or not? Meaning, you're too far downfield (whatever that is) and the play goes to the other side of the field.

Anyone know anything about this rule?

Thanks a lot...

I couldn't find the exact rule, but this might help:

This is a little bit better I think. It's not official NFL rules, but seems to comprehensively answer the question:

[fredp45]

ok, I appreciate the answer to my first question, now, why is that rule in place? Is it a really old rule that doesn't have much meaning or reason anymore or is it because they don't want lineman blocking downfield (if so, why not?) or is it because a lineman would look like a receiver and confuse the defenders into thinking they must cover that player leaving an eligible receiver open? OR, would a team send everyone downfield (like we did as kids) and therefore, make organized football look more like our pickup games?

I know there are still rules in place that came about 40-50 years ago when the game was very different, more of a running game for sure. Evidenced by the fact, Romo already has more 300 yard passing games than Bart Starr and Roger Staubach combined.

Thanks for the quick responses.

There are a couple of reasons for the rule that I can think of off the top of my head:
1. It helps the refs keep track of who is an eligible receiver, and who is not, if only receivers can be down the field.
2. Blockers could be downfield ahead of the receiver, to basically block the defenders from being able to cover receivers. So you could be setting up a screen pass 20 yards downfield without the rule.

Yes, the old ineligible man downfield call. This rule is in place to help keep teams from "flooding" zones with players that would influence the defensive coverage schemes.

Most officials will give you about 2-3 yards downfield before they call you for being downfield.

It is also a penalty for any ineligible receiver to be the first to touch the ball, it is the "illegal touching" rule.

The rule exists because it would give an unfair advantage to the offense if a couple of guards could go downfield to block for a receiver. Imagine if the screen play could be run five yards beyond the line of scrimmage.

It's not really an antique rule.

Thanks again...

Therein lies the problem. Thundersloth and Welch, the last two posters, gave two different reasons:

1) so ineligible receives don't flood an area, requiring the defense to worry about covering them; and

2) so they don't block downfield.

Is this rule in place for both reasons or just one of them?

When this happened to the Skins, vs Dallas, my brother and I each thought it was for a different reason. I thought it was 1) above as I think it would be unfair to send people downfield that are ineligible to catch the ball as that would confuse defenders on who to cover. I didn't believe it's blocking based.

My brother thought it was 2) above. I don't believe 2) is the answer as a flag is thrown whether you're blocking or not...like Casey vs Dallas who was just standing downfield.

Remember, you can't block downfield until the ball has been received whether you're eligible or not -- ala, Devin Thomas getting flagged this weekend vs Eagles for blocking before Santana caught the pass.

Okay, I know, who really cares? I just find some rules worth thinking about and discussing and this one hit me after Casey was flagged for it. I even wonder if the rule shouldn't provide an out if the player isn't near the action. Casey is 4 yards downfield on the right but the play goes deep left.

Anyway...thanks again to the responders.

According to Trevor Mattich, the rule actually states that if Casey had taken a knee there, he would not have been flagged, because he can be downfield so long as he's engaging the defender but once the defender breaks away, he has to go down to one knee.

I'm gonna say it's got a bit to do with both confusing the defensive coverages and blocking downfield.

I'm not sure on the NFL rule but I do know that linemen can be downfield as far as they want blocking on a pass play as long as the pass is completed behind the LOS in the college game. I'll try to research that and get back to you.

[Thundersloth]

I looked a couple of places and really couldn't get a straight answer about the rule. I wish the NFL would just put the rules online, it would make it a lot easier.

I saw one message board where they said that "when the offensive lineman advances beyond the line of scrimmage on a normal play, it tells the defense that a pass will not be thrown on the play. This is the reason that the penalty exists. It would be sending a false message to the defense and would change its defensive reaction on the play. The defense is set up to do different things based on whether the play is a run or pass -- if a tackle hits a linebacker, the linebacker immediately knows it's a run and he doesn't have to worry about pass defense."

But that doesn't sound right to me, I've seen teams do "influence pulls" to draw up LBs, play action draws up LBs and draw plays themselves are meant to deceive LBs.

[Deadskins]

On a draw, the blocking mimics a pass, though. The linemen backpedal instead of driving off the ball, as for a run.

I think the idea is largely to keep the structure of the line of scrimmage intact.

Otherwise you would have 10 eligable recievers and the game would quickly devolve into a game of keep-away.
