Arkansas quarterback Ryan Mallet has defended himself amid rumors of possible drug use. Mallett said at the school's pro day that he's dealt with the same scrutiny since his days as a high school star in Texas. At the combine, he said simply that teams know what they need to know about him. "I answered the same questions about four times, so I don't know what else you want me to say," Mallett said. Representatives from every NFL team were in attendance to get another look at Mallett, who was the SEC's leading passer in 2010. "I thought I had a pretty good workout. It was good to get back and throw with some guys I hadn't thrown with in a while," Mallett said. "They looked really good, so they went out there and made me look good and let it fly a little bit."
