He's historically popular
No matter what side of any kind of Tebow debate you might be on, there's no questioning his ability to draw. In Denver's overtime win vs. the Steelers in the first round of the playoffs, Twitter was flooded with a record 9,420 tweets/second, compared with 4,064 tweets/second at the height of last year's Super Bowl. The game was the highest-rated NFL wild-card game since 1988. This season, Tebow had the No.2-selling playoff jersey in the league. Tom Brady's jersey sold fifth-best.
