A lot of Broncos fans really give Rivers a hard time about his emotions (hey, I get it, he's the divisional opponent).  And, you'll never catch me cheering for the guy.  But, I think he's a darn good QB and teammate/leader.  So far it seems his emotional behavior isn't Siemian's style, but maybe as Siemian establishes himself, we might see some fire come out.  That wouldn't be bad at all.
