I don't know why I read this.  Must be a glutton for punishment.  John Elway has done a great job with the Broncos both on and off the field. Two Super Bowl appearances and one win is not half bad.  Siemian is a good quarterback.  No, he doesn't have the legs or arm of Lynch but neither does Tom Brady. (Granted, no comparison at least not yet - one can hope).  The NFL has been full of great quarterbacks who had less talent than many of their peers.  I like Siemian's intelligence, situational awareness, lack of complaints, toughness.  I suspect he will become much better this year especially if he gets protection and we will see him stretch defenses with longer throws.  Last year he was running for his life and playing injured the last part of the season.  Remember, he won AFC player of the week last year as well.
I do wonder why Sloter wasn't given a shot to be #2.  He plays with confidence and fire.  Chad Kelly will push everyone net year.  He has tons of talent if he can behave.
