Pro set formation (Offense)

"In American football, the pro set or split backs formation is a formation that was commonly used as a "base" set by professional and amateur teams. The "pro set" formation featured a backfield that deployed two running backs aligned side-by-side instead of one in front of the other as in traditional I-formation sets. It was an outgrowth of the original, three running back T-formation, with the third back (one of the halfbacks) in the T becoming a permanent flanker, now referred to as a wide receiver. ...
A common variant of this formation removes the tight end and replaces it with a third receiver in the "slot" position. The formation is utilized to remove a defensive player from the tackle box to give the offense a 7-on-6 matchup.
There are three formations in the pro set of forms: Pro, Ace, and Tree." [Pro set. Wikipedia]

"The I formation is one of the most common offensive formations in American football. The I formation draws its name from the vertical (as viewed from the opposing endzone) alignment of quarterback, fullback, and running back, particularly when contrasted with the same players' alignments in the T formation.
The formation begins with the usual 5 offensive linemen (2 offensive tackles, 2 guards, and a center), the quarterback under center, and two backs in-line behind the quarterback. The base variant adds a tight end to one side of the line and two wide receivers, one at each end of the line." [I formation. Wikipedia]

"In American football, the dime defense is a defensive alignment that uses six defensive backs. It is usually employed in obvious passing situations.
The formation usually consists of six defensive backs, usually two safeties and four cornerbacks, and has either four down linemen and one linebacker, or three down linemen and two linebackers. This formation is to prevent the offense from completing a medium to long range pass play. This may be because the offense's running game is inefficient, time is an issue, or they need a long pass for a first down. It is also used against teams whose pass to run ratio predominately favors pass . The formation, however, is vulnerable to running plays as the formation is missing two linebackers, or a linebacker and a down lineman. A dime defense differs from the nickel in that it adds a sixth defensive back to the secondary. This sixth defensive back is called a "dimeback" (D). The defense gets its name because a dime is the next step up in US coin currency from a nickel. There are also 'quarter" and "half-dollar" formations (each protecting against progressively deeper thrown and more likely pass attempts)." [Dime defense. Wikipedia]
