Stubler on Fan 590 this morning

Guys pressed him on the QB front. Yes Joseph is the starter but if he struggles again next week he will not hesitate to put Bishop in. Pressed farther, are you allowed to play Bishop, Stubler was quite annoyed, I am the coach I play whoever I want?

Why did you bring in a new QB in are you planning to move a qb out? We are always looking to improve in every position and thats not even my dept,. It was a intersetingly hostile interview???
