Question: Did Ron Dundas play a football position for the offense or defense? 

Context paragraphs:
Wheel offense: Wheel offense is an offensive strategy in basketball, developed in the late 1950s by Garland F. Pinholster at the Oglethorpe University.  It is a kind of continuity offense in which players move around in a circular pattern to create good scoring opportunities.  The wheel offense is a popular offensive play, frequently used by teams from middle school to college levels because it can effectively work against any defense, including zone defense and man-to-man defense.

Midfielder: A midfielder is an association football position.  Midfielders are generally positioned on the field between their team's defenders and forwards.  Some midfielders play a disciplined defensive role, breaking up attacks, and are otherwise known as defensive midfielders.  Others blur the boundaries, being more mobile and efficient in passing: they are commonly referred to as deep-lying midfielders, play-makers, box-to-box, or holding midfielders.  The number of midfielders on a team and their assigned roles depends on the team's formation; the collective group of these players on the field is sometimes referred to as the midfield.

Tackle (gridiron football position): Tackle is a playing position in American and Canadian football.  Historically, in the one-platoon system prevalent in the late nineteenth and early twentieth centuries, a tackle played on both offense and defense.  In the modern system of specialized units, offensive tackle and defensive tackle are separate positions, and the stand-alone term "tackle" refers to the offensive tackle position only.  The offensive tackle (OT, T) is a position on the offensive line, left and right.  Like other offensive linemen, their job is to block: to physically keep defenders away from the offensive player who has the football and enable him to advance the football and eventually score a touchdown.  The term "tackle" is a vestige of an earlier era of football in which the same players played both offense and defense.

Running back: A running back (RB) is an American and Canadian football position, a member of the offensive backfield.  The primary roles of a running back are to receive handoffs from the quarterback for a rushing play, to catch passes from out of the backfield, and to block.  There are usually one or two running backs on the field for a given play, depending on the offensive formation.  A running back may be a halfback (in certain contexts also referred to as a tailback) or a fullback.  A running back will sometimes be called a "feature back" if he is the team's starting running back.

Ron Dundas: Ron Dundas (born c. 1934) is a retired Canadian football player who played for the Saskatchewan Roughriders and Edmonton Eskimos, mainly in the Tight end position.  He played junior football in Regina.

Multiple offense: The multiple offensive scheme is an offense used by several teams in United States college football.  It consists of formations and plays from other offensive schemes including the option offense, pistol offense, pro-style offense, spread offense, etc.  The offense is often a balance between the run and the pass, keeping the defense guessing, and allowing the offense to open the playbook and create more chances for impactful plays.  It creates advantages for the offense such as spreading the field with 4 to 5 wide receivers, gaining yards and first downs easily with 2-tight-end sets, and allows the team's offense to not be one-dimensional and harder for the defensive team to scout.

Nickelback (gridiron football): In American football, a nickelback is a cornerback or safety who serves as the fifth (in addition to the typical four) defensive back on the defense.  A base defense contains four defensive backs, consisting of two cornerbacks, and two safeties.  Adding an extra back makes five, hence the term "nickel", which is the name for 5-cent coins in the United States and Canada.  Usually the nickelback will take the place of a linebacker, so if the team were to be in a 4–3 formation, there would now be four linemen, only two linebackers and five defensive backs creating a 4-2-5 formation.  However, some teams will replace a lineman rather than a linebacker, creating a three linemen, three linebacker and five defensive back alignment, a 3–3–5 formation.  If an offensive team always uses three or more wide receivers, a defense may turn to a nickel defense for their base package on most plays.  Usually extra defensive backs, such as a nickelback, are substituted into the defense in situations where the opposing offense is likely to attempt a forward pass, such as 3rd-and-long, or when extra receivers are substituted into the opposing offense.

Tight end: The tight end (TE) is a position in American football, Arena football, and formerly Canadian football, on the offense.  The tight end is often seen as a hybrid position with the characteristics and roles of both an offensive lineman and a wide receiver.  Like offensive linemen, they are usually lined up on the offensive line and are large enough to be effective blockers.  On the other hand, they are eligible receivers adept enough to warrant a defense's attention when running pass patterns.

Cal Hubbard: Robert Calvin Hubbard (October 31, 1900 – October 17, 1977) was a professional American football player and Major League Baseball (MLB) umpire.  After playing football at Centenary College and Geneva College, Hubbard played in the National Football League (NFL) between 1927 and 1936 for the New York Giants, Green Bay Packers and Pittsburgh Pirates, playing the bulk of his career with the Packers.  Hubbard is credited as being one of the inventors of the football position of linebacker.

Pistol offense: The pistol offense is an American football formation and strategy developed by Michael Taylor and popularized by Chris Ault in 2005, while the latter was head coach at the University of Nevada, Reno.  It is a hybrid of the traditional shotgun and single back offenses.  In the pistol offense, also commonly referred to as the "pistol formation", the quarterback lines up four yards behind the center, which is much closer than the seven-yard setback in a traditional shotgun formation.  The running back then lines up three yards directly behind the quarterback, which is in contrast to the shotgun, where they are beside each other.  It is argued that the position of the quarterback in the pistol formation strikes an advantageous compromise: the quarterback is close enough to the line of scrimmage to be able to read the defense, as with run situation sets such as the I formation, but far enough back to give him extra time and a better vision of the field for passing plays, as in the shotgun.  The pistol formation is thus very versatile, particularly if the quarterback himself is a threat to run the ball, which makes it difficult for the defense to correctly anticipate the play.  This flexibility is enhanced by the Read Option, where the quarterback reacts to the response of the defensive players to the snap, and makes a rapid decision whether to hand off the ball to the running back, keep it and complete a pass to a downfield receiver, or keep it and run himself.
