Tim Tebow billboard pops up in Jacksonville (Photo)

It's hard to recall any athlete who has done so much for the billboard business as Tim Tebow — or for outdoor ad space in general.

The Wildcat quarterback had billboards in Denver and once even had a huge Jockey underwear ad hovering outside the Lincoln Tunnel when he was a Jet.

Now, as you can see in the photo below, fans are now buying billboards and making crazy promises to fill EverBank Field if  Jaguars owner Shad Khan will sign Tebow.

This isn't the first time this season that 'Sign Tebow' propaganda has been seen in Jacksonville. During a Week 4 home game, a banner was flown over EverBank Field encouraging the team to sign Tebow.

Can't Khan take a hint? Or does he have a stake in the outdoor advertising business.
