The problem with Trevor is he doesn't make plays.  He will do fine as far as the stats sheets look, but when push comes to shove and the game is on the line, he's nowhere to be found.  Elway's first few years didn't look good on the stats sheet, but everyone knew how great he was, because when the game was on the line he could practically win it himself.  The Broncos had a terrible o-line Elway's first few years, and no running game to speak of, and their wide receivers were suspect.  But Elway got them to play better than they were.  I don't even expect Trevor to be Elway, he's not, not even close.  However that Tennessee Titans game sticks out like a sore thumb, because all he needed to do was get the Broncos in field goal range, and he couldn't even do that.
