Oh I don't care for Big Al and D-Mac either.  I rarely listen to them.  The comments about them from a few other posters here are spot-on.  

Stink is way better.  But yeah, even he has to drift at times in the off-season when there's not a lot of Bronco news.  You can only beat the dead horse that is Trevor vs Paxton for so long before it gets really old. 

I do generally like Tyler.  But also keep in mind his show with Cecil was only on for an hour.  The others have like 3-hour shows.  It's a lot harder to talk Broncos for 3 straight hours when there's just not much going on.  When it's during the season, around the draft, early free agency, etc, Schlereth & Evans were pretty much full-time Broncos without much filler.  (I can't really say for Big Al & D-Mac because I can barely stomach listening to them any time.)
