AJ, I agree it was risky for the HC of the BB to pull Taylor, however, the Bills were tanking badly. Hard to castigate a coach for trying something to halt the slide as this slide is going to result in his slide right out of the HC of the BB job. So what can you change when your D is tanking and your O is tanking? In this instance he tried a QB that had been given some 6 minutes of junk time the previous week in which he went 7-10 for 80 yards. That small stretch of junk time was suggestive of maybe he was an unknown that would surprise. Again risky? Absolutely. Worth a try given the tanking going on? The results suggest that yes it was a failed move.
Fyi, I am(or was) a forced VT watcher (close female friend who is an Alumni). Taylor was not an NFL QB in the waiting at VT. I give Taylor credit for sitting on the bench and learning the craft, learning what he could and couldn't do, then doing it as well as he could (I said exactly that in a post here during the preseason -- even a little waxing poetic). But if Taylor is your QB you are, IMHO, stuck with either needing a shutdown D and potent running game or you are a team relegated to mediocrity. Buff had a decent run game and decent D to start so Taylor worked. Once these two areas started waning you are basically dead in the water with Taylor. IMHO...
