CINCINNATI -- There was a lot made of the Bengals signing of undrafted linebacker Vontaze Burfict, but for a team lacking depth at the position and with three players entering the final year of their contract, it is a low-risk, high-reward move. Burfict's first weekend as a Bengal, which took place at the rookie minicamp, went well for the most part, but coach Marvin Lewis acknowledged that if Burfict is to make the final 53-man roster he is going to have to show something on special teams. "He's a better-conditioned athlete now than he was at the combine and at ASU in March. If he continues to go down that path, he seems bright enough to learn. He seems willing to want change this image people have of him," Lewis said. "He can be a good football player. Learn to bend his knees, play behind his pads, strike people within the whistles and life is good." Burfict said that he wrote letters to all the league's coaches and general managers but that Lewis was the only one who answered.
