Man that was a painful Broncos game today.
Siemian is just plain awful, I know it's trendy to blame the O-line, and I will agree they aren't the best, but Siemian doesn't do them any favors either. The guy can read a defense to save his life, again there were multiple plays he could have had completions where he just plain missed an open guy. He holds the ball way too long, if his first read isn't open he panics. He looks like your prototypical late round journeyman QB who is in over his head.
It's really a shame that we are wasting such a great defense pairing it with such a lousy QB, who can't make plays.
