As great as he was on the field, long-time Pittsburgh Steeler Brett Keisel will always be remembered for his legendary whiskers. His facial hair has its own Facebook page and Twitter feed and has inspired Steelers fans to simply refer to Keisel as "The Beard." However, his impact on Pittsburgh football was a lot bigger than that. After a successful college career at BYU (yes, he was clean-shaven as a Cougar), Keisel was selected in the 7th round of the 2002 NFL draft. He stayed with his team for 12 seasons, helping them win three AFC championships and two Super Bowls—XL and XLIII. Keisel was named to the Pro Bowl in 2010.

Chad Lewis's mission to Taiwan ended up helping the NFL tremendously. After being undrafted out of BYU, Lewis was signed by the Philadelphia Eagles, who were unaware that they'd just picked up the man who would become one of the most accomplished tight ends in franchise history. Lewis spent a year in St. Louis, where he won a Super Bowl with the Rams, then was shipped back to the Eagles. During his second stint in Philly, Lewis was named to three Pro Bowls. He also caught the game-clinching touchdown pass in the 2005 NFC championship game, which sent his Eagles to Super Bowl XXXIX. In 2002, Lewis's mission experience and squeaky clean image prompted the NFL to send him to Taiwan to promote the league.
