Selected by the San Jose Sharks in the second round (No. 35) in the 2005 NHL Draft, the man affectionately known as Pickles was an instant hit, and he became a regular in the Sharks lineup at age 19 in the 2006-07 season.
The 6-foot-1, 205-pound defenseman led NHL rookies in ice time (22:12) and was third on the Sharks. Vlasic was named to the NHL All-Rookie Team along with teammate Matt Carle, the first defensemen from the same team to sweep the all-rookie spots since Nicklas Lidstrom and Vladimir Konstantinov of the Detroit Red Wings in 1991-92. With his patient game, efficient puck-moving skills and ability to take away the puck without resorting to physical play, Vlasic's game is often compared to that of Lidstrom, a seven-time Norris Trophy winner.
