Upon being drafted, he returned to the WHL for two more seasons and was awarded the Doug Wickenheiser Memorial Trophy in 2004 as humanitarian of the year. On February 4, 2005, Coburn tied a WHL record for most goals by a defenceman in a game with 4 against the Seattle Thunderbirds in a 7-4 win. He completed his final year with the Winter Hawks in 2004–05 with a junior career-high 44 points.
