When the Jacksonville Jaguars picked quarterback Blake Bortles with the No. 3 overall pick, and all indications were that the plan was to have him sit for most, if not all, of the 2014 NFL season. Due to where Bortles was at and the play of Chad Henne, the team made the switch early on with mixed results.
Bortles looked like your typical rookie quarterback in the NFL, with some flashes of brilliance and some boneheaded mistakes, but NFL Films guru Greg Cosell said that he learned to bad habits during his rookie season under Jedd Fisch that he will need to correct going forward.
I can't seem to find an archive of the audio, but what Cosell said wasn't really anything damning or surprising about Bortles. It was known that he had mechanical issues he needed to clean up when he was drafted. While you're a starter, there's not a lot of time to work on those during a game week, so it will be a focus this offseason for Bortles to work with quarterbacks coach Frank Scelfo and new offensive coordinator Greg Olson.
