Question: The 1974 Pittsburgh Steelers season was capped off with a 10-3-1 record and the Super Bowl IX championship, which Cornerback, arrived in 1971? 
Context: Super Bowl IX was an American football game between the American Football Conference (AFC) champion Pittsburgh Steelers and the National Football Conference (NFC) champion Minnesota Vikings to decide the National Football League (NFL) champion for the 1974 season.  The game was played on January 12, 1975, at Tulane Stadium in New Orleans, Louisiana, the last pro game at that venue (the game was originally planned to be held at the Louisiana Superdome, but that stadium was not completed yet).  The Steelers defeated the Vikings by the score of 16–6 to win their first Super Bowl. Willie James Williams (born December 26, 1970) is a former American football cornerback in the National Football League and current Head coach for Winston Churchill High School.  He was drafted out of Western Carolina University by the Pittsburgh Steelers in 1993, and spent the first 4 seasons of his 13-year career in Pittsburgh.  He was a key member of the 1995 Steelers team that played in Super Bowl XXX.  From 1997 to 2003, Williams played for the Seattle Seahawks, before returning to the Steelers for the 2004 and 2005 seasons.  Williams had a much smaller role in 2005, but still posted 10 tackles, adding to his career totals of 602 tackles and 26 interceptions.  Williams has the distinction of being the only player from the 1995 Steelers Super Bowl XXX roster to be a member of the 2005 Steelers Super Bowl XL roster.  The Steelers defeated the Seahawks in that game 21-10 (though Williams was not active in Super Bowl XL, and did not dress with pads).  He is also the cousin of Tamera Young of the Atlanta Dream (WNBA). The 2005 Pittsburgh Steelers season began with the team trying to improve on their 15–1 record from 2004 in which they lost to the New England Patriots in the AFC Championship Game at Heinz Field.  They were looking to become the first team in NFL history to complete a 16-game season undefeated.  The Steelers, with the sixth and final seed to the playoffs, became just the second team ever (and the first in 20 years) to win three road games on their way to the Super Bowl.  They defeated the NFC Champion Seattle Seahawks in Super Bowl XL to secure their league-tying fifth Super Bowl title.  In doing so, they also became the first team since the 1970 AFL-NFL merger to win a Super Bowl without playing a single home playoff game. Melvin Cornell Blount (born April 10, 1948) is a former Pittsburgh Steelers cornerback, five-time Pro Bowler and a 1989 Pro Football Hall of Fame inductee. The 2010 Green Bay Packers season was the 91st season in the National Football League for the Packers and the 92nd season for the team overall.  Although they finished with only a respectable 10–6 record, good for a second-place finish in the NFC North, the Packers never lost a game by more than four points, and never trailed by more than seven the entire season, becoming the only team since the AFL-NFL merger in 1970 to accomplish this.  All six of their regular season losses were by a combined 20 points.  They entered the playoffs as the NFC's sixth seed.  After defeating the Philadelphia Eagles 21–16 in the Wild Card round, the Atlanta Falcons 48–21 in the Divisional round and the Chicago Bears 21–14 in the NFC Championship, the team advanced to Super Bowl XLV in which they faced the AFC's 2nd seed Pittsburgh Steelers.  The Packers defeated the Steelers 31–25 to win their fourth Super Bowl and 13th NFL championship.  The Packers became the second overall team after the 2005 Pittsburgh Steelers, and the first NFC team, to win the Super Bowl as a sixth seed, as well as becoming the second NFC team to win three straight road playoff games (the 2007 New York Giants won three straight road games as a five seed). The 1979 Pittsburgh Steelers season saw the Steelers successfully defend their Super Bowl Championship from the previous year as they achieved a 12–4 record and went on to defeat the Los Angeles Rams in Super Bowl XIV.  The Steelers started out to a 4-0 record.  Adding to the previous season, the Steelers had won 12 in a row.  They finished the regular season at 12-4.  In six of those games the opponents were held to a touchdown or less.  In the playoffs Pittsburgh defeated Miami, 34-14 and then for the second consecutive season beat Houston 27-13, in the AFC championship game.  Finally defeating the Los Angeles Rams 31-19 in Super Bowl XIV. Charlie Davis (born November 17, 1951 in Wortham, Texas) is a former professional American football defensive tackle in the National Football League.  Davis was a 9th round selection (229th overall pick) by the Pittsburgh Steelers out of Texas Christian University in the 1974 NFL Draft.  He played for seven seasons in the NFL.  He played for the Pittsburgh Steelers and was a back-up Defensive Tackle and a member of the Steelers first World Championship Super Bowl IX over the Minnesota Vikings, was traded to the St. Louis Cardinals Sep 15 1975, for whom he played from (1975–1979), and the Houston Oilers (1980).  Charlie played the best game of his career in the 1975 NFC Divisional Playoffs against the LA Rams when he recorded 5 sacks and recovered a fumble. Gordon Carr Gravelle (born June 12, 1949) is a former American football offensive tackle in the National Football League.  Drafted out of Brigham Young University in the 1972 NFL Draft, Gravelle spent eight seasons with three teams: the Pittsburgh Steelers (1972–1976), the New York Giants (1977–1979), and the Los Angeles Rams (1979).  He earned two Super Bowl rings in Super Bowl IX and Super Bowl X with the Steelers.  He lost Super Bowl XIV in 1979 with The Los Angeles Rams. James Verle Lash (born November 12, 1951) is a former American football wide receiver in the National Football League in the 1970s and played on three Super Bowl teams.  He attended Garfield High School in Akron, Ohio, the same high school that fellow NFL wide receiver Steve Craig attended.  His five-year pro-career was spent with the Minnesota Vikings in which he helped lead to Super Bowl VIII, Super Bowl IX and Super Bowl XI all coming up a bit short against the dynasty teams of the Miami Dolphins, the Pittsburgh Steelers and the Oakland Raiders. The 1974 Pittsburgh Steelers season was capped off with a 10-3-1 record and the Super Bowl IX championship.  The '74 team became the first team in Steelers history (42 seasons) to win a league title following one of the franchise's greatest playoff runs ever.  After the hiring of head coach Chuck Noll in 1969, Noll signed Defensive Tackle #75 Joe Greene.  He then signed Quarterback #12 Terry Bradshaw in 1970.  Linebacker #59 Jack Ham and Cornerback #47 Mel Blount arrived in 1971.  And in 1972, the Steelers signed a fullback from nearby Penn.  State in Franco Harris.  By 1973, Joe Greene was flanked on the line by Dwight White, Ernie Holmes, and L. C. Greenwood.  In the 1974 draft, the Steelers took no time in signing some more talent for the team.  Wide Receiver #88 Lynn Swann and #82 John Stallworth, Linebacker Jack Lambert, and Center Mike Webster all became future hall of famers.
Answer: Mel Blount
