Evasive D Line

I played against the weirdest D line technique over the weekend.  The guy just sort of stood back and watched the play develop then made his move.  This was great on pass plays as it gave me a chance to set myself but on the run he just sort of held me back with a longer reach stopping me getting any movement happening.  When I tried to just drive through he'd just step away.  Can someone give me some things I can do in my training to get around this?  I tried swiping the arms and all the normal stuff but no success.

Thanks
