The Jaguars have appear to have only targeted two players in free agency so far and it looks like they've got them both. According to Tania Ganguli, the Jaguars have agreed to a two year deal with former Miami Dolphins quarterback Chad Henne.
Henne, 26, is entering his fifth season in the NFL after spending each of his first four seasons in Miami. He was a four year starter at the University of Michigan before being drafted by the Dolphins in the second round of the 2008 NFL Draft. After one year behind Chad Pennington, Henne took over as starter for the Dolphins in 2009 and remained starter for the 2010 and 2011 seasons.
Shoulder surgery in early October 2011 ended Henne's season and effectively ended his career with the Dolphins, where he struggled to ever establish himself as a quality NFL starter.
And no, before anyone asks, Blaine Gabbert is the starter. If Henne outplays Gabbert then the Jaguars have much more significant problems than deciding who starts the 2012 season.
