John-Michael Liles was drafted by the Avalanche in the 5th round, 159th overall in the 2000 NHL Entry Draft. Before joining the Colorado Avalanche, he played college hockey for the Michigan State Spartans, where he was recognized as a star offensive defenseman. During his senior season with the Spartans, Liles led the team in scoring (with 16 goals and 34 assists) while helping Michigan State to a 23-14-2 record.
After scoring 10 goals and recording 24 assists in his rookie season with Colorado in 2003-04, Liles was named to the NHL All-Rookie Team. During the NHL lockout, he played pro hockey in the German League DEL for the team of the Iserlohn Roosters.
Liles returned to the Avalanche after the lockout and had his best season to date, tallying 14 goals and 30 assists for a total of 44 points in 71 games.
Liles is a defender with great offensive potential. He has a great feisty nature that he brings to the ice each and every night, providing his team with enough jam from the blueline to have confidence in their rushing attack. Liles moves the puck well and always skates hard. It doesn't hurt that he has a great shot.
