Who Is Most Responsible for the San Diego Chargers Success in 2012?

I was talking to a BFTBer last night and he asked me, point blank, if the San Diego Chargers are going to be good in 2012. I knew what he meant, were they going to be better? Were they going to make the playoffs? Would they have a chance at the Super Bowl?

I thought about it for a second, explained to him that I don't think A.J. Smith and the Chargers' front office could've possibly done a better job in the offseason than what they did, and then said "We'll see. It's up to David Chao, I guess." That was my snarky way of saying that the biggest thing standing in the Bolts' way was health.

A minute later, I changed my tune a little bit. "It's not all up to Chao. Ryan Mathews needs to have a big year. Ingram needs to be good. The offensive line needs to play to their potential." I drifted off, realizing that a lot of things had to go right for the Chargers to be considered championship contenders this season. I finally settled on "The most important person for the Chargers this year is John Pagano, who is also the biggest question mark. If he can be half of what his brother was as a Defensive Coordinator, the Chargers will be championship contenders. I think. Maybe."

Anyway, my indecision has lead me to use one of my lifelines and poll the audience (that's you!). Have at it.
