Fortunately Denver fans don't bolt.  They've sold out a record home game streak longer than all teams except for the Redskins and have done it since entering the NFL from the AFL.  I'm not quite that old but have been a Broncos fan since the mid 70's and a season ticket holder for 17 years now.  Siemian isn't the only player on the Broncos yet quarterbacks are held to a higher standard, as they should be, but a team's success depends on more than just him.  He's shown he can play in this league.  I'm with the Broncos regardless of a player's success or the team's success.  I don't switch to a different team if my team isn't doing as well as I'd like them.  Every player must prove themself each game.
