Question: What position do both Beniamino Vignola and Gianni Rivera play in football?

Context paragraphs:
Offside (association football): Offside is one of the laws of association football, codified in Law 11 of the Laws of the Game.  The law states that a player is in an offside position if any of their body except the hands and arms is in the opponents' half of the pitch and closer to the opponents' goal line than both the ball and the second-last opponent (usually, but not necessarily always, the last defensive player in front of the goalkeeper).  Being in an offside position is not an offence in itself; a player who was in an offside position at the moment the ball last touched, or was played by a team mate, must then become involved in active play in the opinion of the referee, in order for an offence to occur.  When the offside offence occurs, the referee stops play and awards an indirect free kick to the defending team from the place where the offending player became involved in active play.

Beniamino Vignola: Beniamino Vignola (born 12 June 1959 in Verona) is an Italian former footballer and entrepreneur, who played as a midfielder.  He notably played for Juventus and was part of their European Cup victory in 1985.

Georgios Delikaris: Georgios Delikaris (Greek:Γεώργιος Δεληκάρης) is a former Greek football player, who spent the greatest part of his career at Olympiacos F.C. He is widely accepted amongst fans as one of the greatest Greek footballers of all time, coming in fourth in the Greek vote for the UEFA Jubilee Awards, first amongst former Olympiacos players.  Nicknamed the "Gianni Rivera of Greece", he is also often compared to George Best, due to similarity in appearance and playing style.  Though still revered as an Olympiacos legend, he is also well remembered for his switch to arch-rivals Panathinaikos F.C., for the last three years of his playing career, which ended prematurely, when he decided to retire at the age of 29.

2008 Saginaw Sting season: The 2008 Saginaw Sting season was the first season for the American Continental Indoor Football League franchise, who began play as an expansion team.  Original team owners were Mike Johnson, Mike Trumbull, and Esteban Rivera, who also owned the Kalamazoo Xplosion.  The team was led by former Michigan State quarterback Damon Dowdell, who led the league in passing yards (2,190), touchdowns (54) and completion percentage (62%).  Nick Body was Dowdell's favorite target, leading the league in receptions (78), yards (1,005) and touchdowns (31).  Despite their offensive numbers, neither player won Offensive Player of the Year or the CIFL MVP.  The duo led the Sting to a 10–2 regular season and a playoff berth.  On June 29, 2008, the Sting defeated the Xplosion 41–37 to win the CIFL Championship Game.

2009 Saginaw Sting season: The 2009 Saginaw Sting season was the 2nd season for the American Indoor Football League franchise.  A number of Sting and Xplosion players indicated at the end of the 2008 season that wages were in arrears from the owners.  This led to an investigation of Johnson in his role as Sting general manager.  Trumbull, owner of Triple Threat Sports in Battle Creek, and Rivera, a Battle Creek police officer, have offered a deal to split ownership of the two teams, with Trumbell and Rivera owning the Sting, and Johnson receiving the Xplosion.  Trumbull and Rivera have indicated that they plan for the Sting to move to the new Indoor Football League.  The Sting looked to have put together a promising team with the re-signing of QB Damon Dowdell, and signing 2007 CIFL MVP, WR/RB Robert Height, but the team fared poorly on the field in the IFL.  After a 2-2 start to the season, head coach Karl Featherstone resigned from his position and assistant Jason Lovelock took over as interim head coach.

Charles H. Smith (American football): Charles H. "Fatty" Smith was an American football center who played for the University of Michigan Wolverines football team in 1893 and 1894.  Smith stood 5 feet, 10 inches, and weighed a hefty 230 pounds in 1893.  In 1894, Smith anchored the line for one of the first great Michigan football teams.  The 1894 Michigan team outscored opponents 244-84 and compiled a record of 9-1-1, including wins over Cornell University and the University of Chicago.  Michigan's 1894 victory over Cornell marked the first victory by a Western football school against one of the Eastern football powers.  Up to that point, no Western player had been selected for the annual College Football All-America Teams selected by Eastern football authorities, Caspar Whitney and Walter Camp.  Smith was the standout star of Western football in 1894, and Western football enthusiasts lobbied for Smith to be selected as an All-American.  Whitney and Camp declined the suggestion, and no Western football players would be selected as All-Americans until 1898, when Clarence Herschberger and William Cunningham received the honors.  The resistance to selecting Smith (or any other Western player) as an All-American is reflected in the following newspaper account from December 1894:"Some of the western colleges have developed great players on their teams and this year may claim for them a position on the All American team.  Notably the University of Michigan claims for their center 'Fatty' Smith the supremacy in his position.  But the western institutions have not yet mastered the eastern knowledge of all the details and fine points of the game.  Smith has made a great record against the west and even against Cornell, but the Ithacan center was not a master of his position.  When brought to face a man like the Stillman of today or the Bulliet of last year, Smith would simply be lost and entirely out generaled.  So it would be with all of the claimants for line positions from western teams.  And no one claims for a moment that western back field men could play in the same class with eastern men."
