2012-13: Callahan skated in 71 of 76 games in his second season with Detroit AHL affiliate Grand Rapids. Playing an agitating, two-way game, he scored 11 goals with 9 assists and was -1 with 93 penalty minutes (third most for Grand Rapids). The Griffins finished first in the Midwest Division and captured the Calder Cup championship. Callahan played in all 24 playoff games, scoring 6 goals with 5 assists, and was +1 with 33 penalty minutes.
Agitator/scrapper type player. At 5'11, he won't be a fighter in the NHL, but rather get under one's skin from the fourth line. Has proven that he has some offensive upside, which he has capitalized on by using his willingness to go to the front of the net.
After making his NHL debut in 2013-14 (albeit for one game) it is certainly possible that Callahan could see time with the Red Wings again in the role of a fourth line checker and penalty killer. More likely, however, is that Callahan returns to the AHL's Grand Rapids Griffins due to his non waiver-exempt status.
