Broncos quarterback Tim Tebow will make his commercial debut next week as the first professional athlete to model Jockey underwear since pitcher Jim Palmer in 1980. Tebow will be wearing Jockey Staycool products and will be featured in a blitz of magazine ads and television appearances in the coming days. "People may say it's underwear, but everyone wears underwear -- it's not like I'm doing something risque," Tebow said. "I wouldn't do anything that goes against what I stand for. The whole campaign is very classy."
