Question: The first ever player drafted by the Indianapolis Colts attended what university?
Context: Billy Dale Vessels (March 22, 1931 – November 17, 2001) was a gridiron football player.  He played college football at the University of Oklahoma and won the Heisman Trophy in 1952.  Vessels went on to play professional football with the National Football League's Baltimore Colts and the Western Interprovincial Football Union's Edmonton Eskimos. The 1997 Indianapolis Colts season was the 45th season for the team in the National Football League and 14th in Indianapolis.  The Indianapolis Colts finished the National Football League's 1997 season with a record of 3 wins and 13 losses, and finished fifth in the AFC East division.  The Colts would start horribly, losing their first 10 games, their first 0-10 start since 1986, before an upset home win over eventual NFC Champion Green Bay.  That would turn out to be the only good highlight all season for the Colts, as the team fell to a league-worst 3-13 record, and earned the first overall pick in the 1998 NFL Draft, in which they selected quarterback Peyton Manning in what would be the start of a dynasty for the Colts in years to come. The 2001 Indianapolis Colts season was the 49th season for the team in the National Football League and 18th in Indianapolis.  The Indianapolis Colts finished the National Football League's 2001 season with a record of 6 wins and 10 losses, and finished fourth in the AFC East division.  In the process the Colts allowed 486 points in sixteen games, an average of 30 points per match and the franchise worst since the infamous 1981 Colts who allowed 533.  At the time only the aforementioned Colts, the 1980 Saints and the notorious 1966 Giants (in a 14-game schedule) had ever allowed more points.  This would be the last time the colts would miss the playoffs until 2011. The 1993 Indianapolis Colts season was the 41st season for the team in the National Football League and tenth in Indianapolis.  The Indianapolis Colts finished the National Football League's 1993 season with a record of 4 wins and 12 losses, and finished fifth in the AFC East division.  The Colts would get off to a fast 2-1 start.  However, after that, the Colts would go into a tailspin for the rest of the season, losing 11 of their final 13 games.  The Colts offense was really abysmal during the season, as they would only score 189 points all season, the fewest in the league, and 3 of their 4 wins were by a 9 to 6 tally.  Their only other win with not such a score was their 23-10 win over the Cleveland Browns in week 4.  For the first time in league history, all NFL teams played their 16-game schedule over a span of 18 weeks. The Indianapolis Colts Cheerleaders are the official cheerleading squad of the Indianapolis Colts.  The cheerleaders perform various dances at the Colts stadium Lucas Oil Stadium, and also performed at Super Bowl XLI and Super Bowl XLIV at Sun Life Stadium.  The 2016 squad currently has 28 members.  The squad was the first cheerleading squad in the NFL, being formed in the same year as the team's inception (1954) by two women.  The squad originally consisted of ten girls with white boots, crew-neck sweaters, blue scarves and a blue skirt with grey kick-pleats as uniforms.  The squad had a horse as a mascot, and often marched with the Baltimore Colts Marching Band, which was left behind in 1984 when the Colts moved to Indianapolis.  The squad's annual auditions feature hundreds of women, with the group's "Audition Showcase" taking place at venues around Indianapolis.  The squad has a show troupe, which travels to various cities to entertain fans.  The Colts Cheerleaders release an annual swimsuit calendar.  The team has a "Junior Cheerleaders" program, in which a team of 300 girls aged 7 to 14 perform at Lucas Oil Stadium and various appearances. Ryan LaCasse (born February 6, 1983) is a former American football linebacker for the Indianapolis Colts, primarily as a special teams player.  He was originally drafted in the 7th round in 2006 NFL draft by the Baltimore Ravens but was traded to the Indianapolis Colts.  He played for the Colts on their Super Bowl XLI championship team that beat the Chicago Bears. Leonard Coleman (born January 30, 1962) is a former American football player who played cornerback in the National Football League for the Indianapolis Colts and San Diego Chargers from 1985 to 1989.  He played college football at Vanderbilt University and was drafted by the Colts in the first round of the 1984 NFL Draft, the first player drafted by the team following its relocation from Baltimore. Eugene Daniel Jr. (born May 4, 1961) is a former professional American football cornerback who played 14 seasons in the National Football League (NFL) for the Indianapolis Colts and Baltimore Ravens from 1984 to 1997.  Daniel attended Louisiana State University.  He was drafted by the Indianapolis Colts in the 8th round of the 1984 NFL Draft.  In 1985 Daniel tied Albert Lewis of the Kansas City Chiefs for the AFC lead in interceptions, with 8.  In 1995, Daniel recorded the longest interception return in Colts history, scoring on a 97-yard interception against the New York Jets.  During his 12 years with the Indianapolis Colts, Daniel was a fan favorite and held many longevity records since surpassed by quarterback Peyton Manning. This is a list of NFL Draft selections by the Indianapolis Colts.  The first draft that the current incarnation of the Colts franchise participated in was 1953, in which they made halfback Billy Vessels of Oklahoma their first ever selection. The 2009 Indianapolis Colts season was the franchise's 57th season in the National Football League and the 26th in Indianapolis.  It was the first season since 2002 that the Colts did not have Tony Dungy on their coaching staff, due to his retirement from coaching.  The 2009 Indianapolis Colts improved upon their 12–4 record from 2008 as well as winning their sixth AFC South division championship in seven years.  The Colts also clinched the #1 playoff seed in the AFC.  The Colts became the sole undefeated team after week 15.  The following week, the Colts lost to the New York Jets after benching their starters.  During the playoffs, the Colts defeated the Baltimore Ravens in the divisional round and the New York Jets in the AFC Championship game, but lost to the New Orleans Saints in Super Bowl XLIV, 31–17.
