On Squib kicks:
There is alot of debate on the use of squib kicks. As has been said, they are almost exclusively used on kickoffs near the end of a half. The ball is kicked low across the ground, typically down the middle of the field.
The real question is why. As has been said they generally are believed to offer a slimmer chance of a long return. This may be debatable, but the downside is you are virtually garunteeing that the team will take possesion near the 35 yardline or better. Its becoming unpopular to use squib kicks under any circumstances except when the clock is expected to run out during the kickoff. In otherwords, a case where the only way the team can give up a score is if the ball is run all the way back.
The reason squib kicks are thought to be safer plays is because most kick returns are designed to allow the blockers to set up a wall or a wedge in the time when the ball is high in the air. By kicking the ball shorter, but on the ground, it gets to the recievers faster, therefore disallowing the chance of a effective blocking scheme developing.
This is not true, the ball gets downfield much faster than an arching high kick. The ball gets there so fast that the blockers can’t set up, but it also means the coverage doesn’t get downfield as far before the return either. Its a double edged sword, and is the major reason why squib kicks usually offer such good field position. The majority of well kicked squibs are fielded at about the 5-10 yardline much like a typical kickoff, the return man however can usually make 15+ yards before even encountering a defender.
This reason is why squib kicks have become somehwat less commonly used. In the 80s you used to see a squib kick on nearly every kick with 2 minutes or less remaining. With the recent ability of QBs (and the West Coast offense) to drive the field in the 2-minute drill (read: Montana, Elway, Marino, Manning, Favre) for a score, its become a better gamble to kick it long than to allow for better field position. In the past when running games were the focus of nearly every offense, field position was less important in a short-time game, and the real risk was the big return. The odds of giving up a big return were better than the odds of a QBs driving the field in 90 seconds. With the new offenses, and the speed of kickoff coverages returns for TDs are getting rare and last minute drives are getting more common. In short, a good coach won’t squib kick unless the opposing offense is really bad, or the time is virtually nil.
On Eligible Recivers:
There are only ever 6 eligible recievers allowed on a given play. 4 of which are backs (QB, FB, RB or a flanker). Backs are simply any player lined up off the line of scrimmage. You must always line up with 7 men on the line of scrimmage. of the 7 men on the line of scrimmage only the players lined up on the end of the line are eligible recievers. These are typically Tight Ends or Split Ends. The term Wide Recievers is a generic term which doesn’t necessarily imply the man is on or off the line of scrimmage. All this said, a player is an “eligible reciever” based on where he is positioned at the snap following the above rules.
This isn’t nessecarily true. It implys that as long as a lineman declares himself eligible to the ref, he is…not true. The case you are indeed referencing is when a tackle declares himself eligible. A tackle may declare himself eligible if, and only if, he is the end man on the line of scrimmage. The act of declaring himself is because he typically doesn’t wear a permitted recievers number, and because the team has unbalanced the line of scrimmage.
The ineligible man downfield penalty is typically called when a ineligible reciever is more than 5 yards downfield on a pass which crossed the line of scrimmage. These are usally lineman on screens or broken plays. It could however be a tight end who is covered (meaning both lined up on the line of scrimmage on the same side of the ball) by a split end, or having two split ends on the same side of the ball. These formations are likely mistakes, but as long as they have the right number of men on the line of scrimmage, its not a penalty unless the inside guy goes downfield.
This is not true, a reciever who is out of bounds, and then comes back into the field of play and is the first one to touch the ball upon retunring to the field is guilty of “illegal participation”, not “ineligible man downfield”.
The difference is that regardless of where the ball is thrown, a play is a penalty if there is an illegal man downfield during an attempted pass. With “illegal participation” it is only a penalty if THAT player is thrown the ball, and he still can legally block for another ball carrier on that play.
