In the 2007 NFL Draft, the Jaguars used their first-round pick (21st overall) to select Florida safety Reggie Nelson. On June 15, 2007, the Jaguars released veteran strong safety Donovin Darius, who had seen diminished playing time in previous years due to mounting injuries. On August 31, 2007, the Jaguars announced that long time back-up quarterback David Garrard would start for the team, ahead of former first round draft pick Byron Leftwich, who was released in the teams final roster cuts. Garrard led the Jaguars to an 11–5 record and a wild card spot in the 2007–08 NFL playoffs. The Jaguars defeated the 2007 Pittsburgh Steelers season 31–29 to win their first playoff game in almost eight years and their first road playoff win since 1997. It was also the first time in the 50+ year history of the Steelers that they had been beaten twice at home by the same team in the same season. However, in the divisional round, the Jaguars fell to the then-undefeated 2007 New England Patriots season; the teams were tied at halftime, but the Patriots pulled ahead and won 31–20. Tom Brady completed 26 of 28 passes in this game, being pressured by the Jaguars defense only once, on the first play.  This game, more than any other, gave the Jaguars front office a strong desire to upgrade the pass rush during the offseason.
