I agree, but at the same time it's understandable why he is frustraited given that he probably is somewhere between 20-32nd best QB in the world which suggests he should start.
As we all know, bottom 1/3rd is not acceptable and teams will look to start worse/unproven guys hoping to get into the top 1/3rd ... but I can't fault him for feeling like he should start when a bunch of guys worse then him have secure starting gigs.
