As a left or right fullback, you will often mark your opponent's nearest forward or protect his/her flank, anticipating the opponent's arriving wingers. You will also play an active role in your team's attacking efforts, so you must stay wide, make overlapping runs, and push up the side. A good left back should be able to score goals.
Fullbacks are key players in any football team. If used properly they can give their team an advantage by shielding the defense from attack or by opening up space for teammates. However, if not done right then it can also be a big risk for the team because you can't have too many people on the field at one time. Therefore, it is important that you know what skills and attributes are needed from a fullback.
Size isn't everything when it comes to football players but it does help. Fullbacks need to be strong and fast to withstand frequent tackles and keep up with opponents. They also need to be aware of where they stand on the field relative to the rest of the team and take responsibility for their area. Finally, they need to have good ball control skills as well as scoring abilities.
Left backs tend to get more attention from opposing teams than right backs because they are responsible for defending against crosses into the box. Therefore, they usually want to put themselves in a position to win challenges and intercept passes.
According to Expert Football.com, right backs aggressively participate offensively by staying wide and making overlapping runs to stretch the defense apart. Essentially, the fullback joins the offensive side on aggressive plays as an extra man for the other team to worry about. On non-aggressive plays, they simply protect the cornerbacks while providing depth at the position.
Right backs usually are large players who can handle themselves well in traffic. They are expected to be strong enough to knock down passes at or behind their line of scrimmage. Most have good ball skills and can make interceptions or recover fumbles. They may also be called upon to fill in at multiple positions if needed. For example, they could be asked to line up at left cornerback if the opposing team has a smaller player who can cover better there.
Right backs typically come from physical backgrounds such as college football or professional sports. Many were either defensive linemen or linebackers before being drafted by teams as fullbacks. Some former players who now work as coaches include Brian Kelly (former Notre Dame quarterback), Mike Singletary (former Chicago Bears linebacker), Thomas Davis (former Carolina Panther linebacker), Jeremiah Ratliff (former Dallas Cowboy running back), Shawn Bryson (former New York Jets running back), and Ryan Nall (former Tampa Bay Buccaneers special teams player).
Modern-day left and right defenders (full backs) play an essential part in an offensive team's play since they generally supply width with overlapped runs and crosses into the box, with wide midfielders retaining their position to be able to step in for the full back if the team loses possession (player rotation).
Leftbacks usually focus on defending their flank while maintaining a strong position between the lines of the field. They are assigned the role of preventing opponents from reaching the ball first or creating opportunities by hitting long passes. Unlike centerbacks who stay put, leftbacks often roam around the pitch looking for space to make a run. Sometimes they even start attacks by dribbling past opponents.
Rightback players defend the other side of the field, which is why they are also called "flanks". They like to get forward as much as possible, looking to join in the attack or simply provide cover for teammates. Rightbacks can score goals and create openings for teammates by taking advantage of loose balls or intercepted passes.
Both fullbacks have similar roles on the field, but they play them differently. This is because each player has specific strengths and weaknesses. For example, a leftback can jump higher than a rightback, so he would be better suited to heading away corner kicks instead. However, a rightback can cross the ball better than a leftback, so he would be more useful in attacking plays.
One of the positions on a rugby league football team is fullback (or full-back). Fullbacks are therefore the final line of defense, tackling any opposing players and retrieving the ball from any kicks that make it through their teammates. They also have responsibility for some simple passes when needed.
In rugby union, the term "fullback" is used less frequently but still applies to those players who can kick long distances and take high balls over the top. In addition to their role as kickers, they are often required to move up the field if their team is under pressure or needs a extra player on the field. Although they are usually well-trained in the art of hand-off, they do not take part in that phase of the game.
There are generally two types of fullbacks in rugby: ones who play at outside-center; and ones who play at inside-center. The outside-center plays on the side opposite to where the try is scored while the inside-center does so on the side where the try is scored. Both types of fullbacks are involved in the attack and defense of the match. However, because the inside-center is on the same side as the try scorer, he is able to contribute more to the offense.
Fullbacks don't always have to be large men.
Two center backs will hang back to guard the goal in a 4-4-2 system. 3/2-Fullback (LB, RB): The back defenders on the left and right sides of the pitch, often known as outside fullbacks. They tend to be tall players with good stamina who can also put in some accurate crosses from the wing. Wingback (RWB, LWBR): Similar to the outside fullback, but playing on the inside instead. They usually have more skill than their outside counterparts and are expected to provide more of an offensive threat. Inside forward (IIAF, IIAF): These players act as secondary strikers, scoring goals when needed. They tend to be quick and agile players with good technique, who like the fullbacks, can also cross the ball.
In a 4-2-2-0 formation, both fullbacks would normally play up front along with the inside forward, while the wingbacks would defend against opposing forwards. However, due to injuries or tactical reasons, coaches may decide to pinch inside, putting one of the wingbacks into the middle. This creates a hole in the defense on the side where the pinch happens, so it's important that the coach fills this gap quickly by bringing someone else into the middle.
As for the centers, they work closely with the fullbacks and inside forward to protect the back four, while the wingbacks focus on attacking plays.
