Choosing a starting quarterback based on a couple quarters of semi-competitive pretend football would be so obviously non-scientific that I find it very hard to believe someone as analytically-minded as Chip Kelly would even consider it.
Over the first two games, Foles and Vick will get, what, maybe five series apiece? That's a tiny sample size.
In the 2012 preseason, Peyton Manning threw three picks and generally looked like a guy whose arm was maybe never coming back. Nick Foles threw for six touchdowns. Who wins the job?
Let's say, for the sake of argument, that the competition between Vick and Foles is so close after months of workouts, meetings, minicamps and August practices that it's impossible to choose a starter. A couple quarters of preseason action won't prove anything. Guys get hot, they blow blocks, they make amazing catches ... that's how the decision is made?
And if the choice comes down to that slimmest of margins, why would the quarterback shuffle end when the season begins? Every game is going to give you more evidence than you got during the preseason.
I think Chip knows exactly who his starter is going to be; he's just hoping the preseason makes it easy to sell that choice to his team.
I wonder how often Belichick will blitz Vick tomorrow night. Or how often Foles will run the read option.
