Who's the biggest disappointment at the half way mark?

1 - Jones. Having just signed a 3 year extension it is dumbfounding for his play to drop off this fast.
2 - Zeitler. Extremely disappointing to see him playing this way in his 5th year going after a contract.
3 - Ced. Yes, he is a young player in the NFL. Yes, his body isn't exactly built for RT. Nevertheless, the expectation for a high round OL player is better than what he has displayed.
