The Blake Bortles era has begun in Jacksonville and that is a good thing. He is an athlete, which makes all the game film with Chad Henne as QB fools gold.

Big underdogs have long been a great play. Going against favorites of 10.5 or higher winning percentage of .200 or higher is 425-343-11. Underdogs of 10.5 or more after week 2 (when markets really start overadjusting) are 397-317-10.

The Chargers are yet again very high on our list of predictably unpredictable teams. They have played well this year, now have far and away their easiest game. This means it will not be easy.

With interior offensive lineman Rich Ohrnberger dealing with a nagging back issue that kept him off the practice field this week, the San Diego Chargers could be starting their third different center in four weeks.

Ohrnberger is listed as doubtful on the final injury report for Sunday game against the Jacksonville Jaguars. If he cannot go, third-round selection Chris Watt could get his first career start for the Chargers. It would be San Diego third different starting offensive line combination in four weeks.

Center is the most important position on the OL. The Chargers also could be down to two healthy tight ends on Sunday. A limited participant due to a hamstring issue on Thursday, Ladarius Green did not practice on Friday and is listed as questionable. Blocking tight end David Johnson also did not practice on Friday, and is listed as questionable with a shoulder issue.
