Footage of Broncos receivers Emmanuel Sanders and Courtland Sutton fighting has surfaced.  The two were on the sidelines when the fight broke out.

These weren’t two guys battling each other during a drill.  They weren’t even on the field when the fight broke out and punches were thrown. 

That suggests that there might be some real issues behind the scenes between them.  They later squashed the beef, but someone should probably keep an eye on them.
