Chad Henne finished the season strong, throwing at least two touchdown passes in Weeks 13 through 17. He's been named the starter over rookie Blake Bortles to open the season.
The Jaguars drafted Bortles third overall for a reason. At some point this season, he's likely going to start.
Unless Henne really catches fire - and he's had his moments - at some point he'll give way to Bortles. It probably won't be for at least a few weeks since the Jaguars don't want to throw the kid to the dogs, but it makes Henne a risky proposition for fantasy owners.
