Add "TMZ Sports reporter" to Joe Theismann's legendary resume -- 'cause the NFL icon just locked up an exclusive with Von Miller!!!
So, we were talking to ex-Washington Redskins QB about the big trade for Alex Smith and where he thinks his pal, Kirk Cousins, should end up next.
That's when Von crashed the interview -- and told Joe he'd be ALL ABOUT getting Cousins in Denver!
It's a great moment.
The good news for Von ... the Broncos are "poised to make a run" for Cousins, according to Ian Rapoport.
