A typical Single set back formation, many variables can be implemented, but this is the basic setup teams use

Single set back (also known as the "Lone Setback" or "Ace" formation or "Oneback" or "Solo") is an offensive base formation in American Football which requires only one running back lined up about five yards behind the quarterback. There are many variations on single back formations including two tight ends and two wide receivers, one tight end/three wide receivers, etc. The running back can line up directly behind the quarterback or offset either the weak side (away from the tight end) or the strong side (towards the tight end).

This formation has gained popularity in the NFL as teams have started trading out a fullback, or blocking back, in favor of another wide receiver or tight end who is usually faster and better able to receive the ball, while still helping the run game with down-field blocks. The effectiveness of the formation is further increased if the team has athletic tight ends with good hands, thereby increasing the versatility of the formation. It is, moreover, good for bootlegs and reverses.

Single-back offenses have gained popularity due to zone blocking and advanced defenses. There are several combinations of single back formations that are used in Division 1 and NFL football. Speed offenses will use single back because the defense still has to respect the run out of these formations since you can line up many tight ends and still have a down field running game. Single back offenses create match-up problems in the defense. Linebackers will often have to cover receivers in passing routes while defensive safeties are used more to come up and stop the run on the line of scrimmage. Teams that run a single-back offense typically rely on quick receivers that run great routes, balanced tight ends (blocking/receiving), intelligent, shifty running backs, fast and intelligent offensive lineman, and a quarterback that can read defenses and make safe throws under pressure. Single-back offenses are more common in the NFL than in college or high school.
