Everybody talks about how much the Hawks had to change over the summer, and while it certainly is significant for one summer, check out these other team revamps:
Anaheim Ducks:
Pre-08/09 (Depth Chart by The Hockey News) vs. pre-10/11 (Depth chart by me, including assumptions about Kariya and Selanne)
Kunitz - - Getzlaf - - Perry---------------------------------Ryan - - Getzlaf - - Perry
Sutherby - Morrison - Marchant-------------------------Kariya - Koivu - - Selanne
Moen - - Pahlsson - R. Niedermayer--------------------Blake - Marchant - Lupul
May - - - Carter - - Ryan--------------------------Beleskey - Chipchura - Voros/Parros
S. Niedermayer - Pronger----------------------------------Visnovsky - - Sbisa
Schneider - - Beauchemin----------------------------------Sutton - - - Lydman
O'Donnell - - Huskins------------------------------------Mikkelson - Festerling
Montador - - - Evans--------------------------------------Brookbank - Syrvet
Giguere - Hiller--------------------------------------------Hiller - McElhinney
Tell me that's not a major revamp (though obviously over a larger span of time).
More to come on this later.
