The 49ers gave DL Glenn Dorsey no assurances on his role when they signed him to a two-year, $6 million deal on March 13. "No, I'm coming into it trying to play whatever they want me to play," he said. "I don't have no set spot." Dorsey is penciled in (lightly) at nose tackle, but at 6-foot-1 and just over 300 pounds, it's not an ideal position in the Niners' 3-4. The 49ers would prefer Dorsey to fill Ricky Jean-Francois' shoes as a utility lineman capable of backing up all three positions up front.
