I would like to see 7.4 yards per attempt.
I'll take my chances in the victory column and everywhere else if Tannehill reaches that level.
This is a good read on the matter, describing how interceptions can be overrated. Exactly. And that means less weight toward passer rating for predictive purposes. I'm not giving away my betting related formulas but yards per attempt with some adjustments is best, as this article describes:

Out of all of the stat websites you have linked, this guy is the only one who built a sound statistical model. He even tests the significance of the independent variables in his models (p-values) which many fail to do, and he tested them at several different confidence intervals (up to 90%). Very nice.
