Dorsey was the No. 5 overall pick of the Kansas City Chiefs in the 2008 NFL Draft, and although he never turned into a superstar, he is a solid player who will help improve the depth on the 49ers defensive line. Dorsey was limited to four games in 2012, hampered by a pair of calf injuries.
Drafted as a defensive tackle, Dorsey was moved to defensive end when the Chiefs changed to a 3-4 defense. His best statistical season came back in 2010, when he totaled 51 tackles and two sacks.
The Chiefs were trying to work out a deal to resign Dorsey, despite him not living up to his draft status, but the 49ers swooped in to grab Dorsey in a free agent market with a limited supply of interior linemen. Jim Harbaugh and the 49ers coaches have a way of getting the best out of their talent, and at 27, Dorsey could find his best years are ahead of him.
