The season is lost. The only thing Josh McDaniels has going for himself is to show some kind of innovative, entrepreneurial mindset that would give Broncos owner Pat Bowlen -- to say nothing of Broncos fans -- reasons to bring him back next year.
In other words: McD has nothing to lose by changing things up. He has nothing to lose by playing Tim Tebow. If anything, it would make the team must-see, in an otherwise lost season.
So why wouldn't he?
