Ladies and gentlemen, your 2012 Jets!
The Jets are 8-point home underdogs Monday Night vs. the Texans (the biggest home underdog role in Rex Ryan's coaching career). If Tim Tebow were announced to be the starter, Vegas projects that those odds would not change in any way. This fact implies that Vegas considers Tim Tebow to be an equal quarterback to Mark Sanchez.
That said, we imagine both of them would have quite different experiences in Vegas.
