The Mac's Tournament is perhaps best known internationally for the defection of Petr Nedved following the Championship game back in 1988. When the trophy was brought out on the ice they looked for the team captain to give it to but Petr was already making his way to a waiting car outside the Olympic Saddledome. The Czechoslokavian government was not impressed. Throughout the years a ton of future NHL stars have played in the Mac's including of recent memory Sidney Crosby (two years in a row with different teams - Dartmouth Subways and Shattuck St. Mary's), Zach Parise, Ryan Malone, Jarome Iginla, Nikos Tselios, Mike Modano, Jay Bouwmeester, and the list goes on and on. 7 solid days of great hockey action.
I imagine that the Marlies tournament has a similar pedigree.
