Pretty sure you're taking it too seriously bro. How good he is has nothing to do with it. Someone took a picture, it looked funny, people mock it. It's pretty simple. And Tebow has a bandwagon because of what he did in college, not just the in NFL. 2 national championships and a Heisman aren't something to just ignore once he hits the Combine.
PS. Again, 2011 Broncos ≠ 2001 Patriots
