I'm not just saying stuff. Regardless of how he is listed, he took a few reps at QB in OTAs but there is not a single report of his actually taking reps running the new offensive scheme during training camp. He did run some Wildcat and they have "Taysom plays" but he's not really being used as a QB. And, since they switched the entire offensive system, he has zero experience running the new offense as a QB. That is unless you count the "Taysom" plays which are really just Wildcat plays with some wrinkles thrown in to keep the defense honest.
Taysom simply can't start a game or even come in to finish a game without having worked in the new system. It's not the old days where he knew the Payton system and had plenty reps in it so he could be used as a legit QB. If they ever use him to close out a game it will just be to run out the clock in the Wildcat or on a trick play.
How he is listed on the roster is only of interest to fantasy football players.
