This formation was the most common in football in the 1990s and early 2000s, so well known that it has even inspired a magazine title, FourFourTwo. The midfielders are required to work hard to support both the defence and the attack: typically one of the central midfielders is expected to go upfield as often as possible to support the forward pair, while the other will play a "holding role", shielding the defence; the two wide midfield players must move up the flanks to the goal line in attacks and yet also protect the fullback wide defenders."

"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]
