‘Jackson, who received his psychology degree from Nebraska, has been the target of more than one raised eyebrow since he joined the Bills last year as a seventh-round draft pick. "My high school teammates used to say, "Sheldon was one of those branches that fell off the tree a long time ago. He’s just doing something his own way,’ " Jackson said. "I’m a team player, but when the pads come off I enjoy my own little world. It’s definitely different. To me, I’m OK. Everybody else is insane. Everybody else is a little weird. I love the way I see things through my eyes." The 6-foot-3, 237-pounder has a few idiosyncrasies, especially for a professional football player. He claims he doesn’t know how to draw, but wants to be a tattoo artist. He has five tattoos himself, including depictions on his back of his mother, brother and sister. While some Bills drive new Hummers, BMWs, Jaguars and other prestigious cars, Jackson’s fleet consists of an 1982 Chevy Monte Carlo, a ’95 Chevy Z-71 pickup truck and a ’77 Harley-Davidson Shovelhead. But one eccentricity stands out more than the others. In fact, 20 things stand out. Jackson polishes his finger and toe nails.’
