There's just a lack of accountability with this guy. There were numerous times he should have been benched last season, yet he wasn't. The Rams game had multiple times where he should have ridden the pine in favor of Bush or DHC. After the Jefferson touchdown, he should have been benched. After the breakdown on the Kupp TD or the big Higbee play, he should have been benched. His job is to prevent the big play, and he failed spectacularly. He wiffed on the tackles, most memorably the one that allowed Kupp to convert a 3rd and 9. How much worse could Bush or DHC have been?
I think he could probably learn from riding the pine for a while.
