I think it was the Pitt game in 2008. He changed a play near the end of the 1st half. Not sure if they scored, but it was the situation you described. He was instructed to basically eat the clock, but Stanzi went for 1st downs.
He was benched the reminder of the game, and it cost us the win. We don't lose that game if Stanzi is the one who gets the reps in the 2nd half.
i also agree with the poster above who mentioned that we'll see a different CJB this year. I think he'll still let it fly a little bit, mainly because we have NO BACKUPS capable of stepping in and playing. But if KF is still here for 2016, CJB will become check down charlie because if he doesn't, he will get pulled as the QB's will have more experience.
I think the same applied to Stanzi in 2009, we saw how raw JVB was, so he had more free reign to let it rip.
I do think JVB got the worst of it tho in 2012. Dude threw it around the field when he was confident. then in 2012, we have GDGD trying to mesh with Coach Campbell and the QB and WR had no freaking clue what was going on. But it didn't help the scheme was the worst in college football. I was at the PU game where threw a 1 yard pass for 4th and 2 and allowed them to kick the FG to win.
I hope CJB airs it out this year, cause next year he may not have the option.
