He isn't "terrible," as one poster said, but he clearly cannot make quick decisions and anticipate routes. He's got to wait for the perfect hole. On one play, he had a clear six, but he waited too long because he was scared to throw it. In the NFL, this is not sustainable.
On the positive side, with the exception of the last play, he doesn't give the ball up. He is extremely mobile, but I don't know why he didn't do it today. His offensive weapons, sans McCoy, are the worst in the league. Zay Jones thus far looks really bad. And we're without Matthews and Clay. Last year, he had one of the best deep balls in the league. I don't think there's been one all year. This is a direct result of the way below par wide receivers we have. And, maybe, the offensive coordinator.
Bottom line, today: There were points to be had, but he didn't seize it. However, not too many quarterbacks could've done a lot with these "weapons."
