2008-09: Willie Coetzee skated in 72 games for Red Deer as an 18-year-old in his first full season in the WHL. Coetzee scored 18 goals with 24 assists and had 42 PMs; he had a -9 plus/minus as the Rebels finished last in their division.
2009-10: Coetzee signed a three-year, entry-level contract with Detroit after playing well in the 2009 Traverse City Tournament and went back to Red Deer for his second year in the WHL. Without fellow Red Wings' prospect Landon Ferraro as his center, Coetzee was the Rebels' leading scorer with 29 goals and 52 assists and was +10 with 32 PMs. Coetzee scored one goal and was -3 in the Rebels' four-game playoff series with Saskatoon.
2010-11: Coetzee started the year with Grand Rapids, but worked himself out of the line-up (5 assists) after 25 games due to lack of production. He spent the rest of the season as a member of the ECHL’s Toledo Walleye, scoring 9 goals and 11 assists for 20 points in 36 games.
2011-12: Coetzee spent the entire season with Grand Rapids in his second pro season. After scoring goals in the first two games for the Griffins, he saw mostly lower line duty – scoring 11 goals with 11 assists in 61 games – and was minus-six with 25 penalty minutes. The Griffins missed the AHL playoffs; finishing fourth in the North Division.
2012-13: Coetzee appeared in one game with AHL champion Grand Rapids and was the leading scorer for the ECHL's Toledo Walleyes in his third pro season. He was -1 with no points or penalty minutes in his only game with the Griffins. Coetzee scored 28 goals with 40 assists and was +6 with 22 penalty minutes in 64 regular season games with Toledo. The Walleye finished second in the North Division and lost to first place Cincinnati in a first round series. Coetzee had 4 assists and was -4 with 2 penalty minutes in six playoff games.
A pure offensive player. Coetzee is highly skilled and has soft hands. He is an adept playmaker, and also possesses a good, hard shot. Has very respectable foot speed that translates into more offensive opportunities. His main issue is a lack of size, as Coetzee may not have the physical prowess to compete at the pro level.
Though he had a stellar offensive stat line with the ECHL's Toledo Walleye, Coetzee could not crack the Griffins AHL lineup. He will look to establish himself with the Griffins in 2013-14.
