I think it's fair to say Holland was heavily responsible for the success of the 2008 Cup squad. Without a doubt beyond Lidstrom and Holmstrom this team was rebuilt quickly after 2002.
Drafts: 04 Franzen (3rd round), Hudler 02 (2nd round), Kronwall 00, Filppula in 02 (3rd round). Datsyuk (98) and Z (99). Pretty amazing success from those later picks.
Mentioned was Stuart but cannot forget other players brought in who were factors. Chelios traded for in 1999. Samuelsson was picked up in 2006. Biggest of all was acquiring Rafalski for that season!
Much of this was sheer luck and favorable conditions Holland was granted from Devellano, especially having a mentor like Bowman to follow. No matter the 2008 Stanley Cup was a great accomplishment and we have to give Holland credit for his part in run.
