The statistics between those two are very misleading, based on the number of snaps (and this disparity is why you used them). Dividing by the number of attempts is a nice way to compare two players who both started. But Tune's statistics have to be labeled as "incomplete" as there just isn't enough data there to make a comparison.
And that is why you are posting this "analysis". Tune's stats being incomplete prevent any of us from being able to say that he couldn't win the starting job.
This spring will be interesting. I think it will remind folks why Riley was one of the top atheltes in the nation out of HS, why he was a Parade All American; and why folks lined up to recruit him.
So if Riley wins this competition; will you then post how Chico can't identify QB talent? Or will it be a triple-secret conspiracy based on language in his contract (written in invisible ink)?
