I took a look at the Seahawks official roster as listed on NFL.com and made a list of the players that John Schneider and Pete Carroll have brought in. I wanted to compare the PC/JS players vs what was left from prior regimes. The results of my collection were pretty amazing to look at. In just over a year, almost the entire roster has been turned over. Keep in mind some of these players are free agents, but right now are listed on the official roster - I included a note next to free agents on whether or not I believe they will be re-signed.
Here are the 58 (out of 85 Seahawk players NFL.com has currently listed on the roster) players that John Schneider and Pete Carroll have brought to Seattle - in JUST OVER ONE YEAR'S TIME (FIFTY-EIGHT):
QB:
Losman, J.P. (most likely won't be re-signed)
Whitehurst, Charlie
OL
McQuistan, Paul
Jeanpierre, Lemuel
Fanaika, Paul
Moffitt, John

----------------------------------------------------------------------------------------------
Now, take a look at who was left from the prior front office and coaching staffs: Out of the 85 total players officially listed on the Hawks' roster, only 27 are left over from over one year ago. Crazy.
QB:
Hasselbeck, Matt (will possibly be re-signed)
OL
Gibson, Mike
Unger, Max
Spencer, Chris (most likely won't be re-signed)
Locklear, Sean (most likely won't be re-signed)
Willis, Ray (will possibly be re-signed)
RB/FB
Forsett, Justin
TE
Carlson, John
Morrah, Cameron
WR
Butler, Deon (possible roster cut, injury PUP in 2011)
Obomanu, Ben
DL
Bryant, Red
Cole, Colin
Mebane, Brandon (most likely won't be re-signed)
Terrill, Craig (most likely won't be re-signed)
DE
crickets..
K
Ryan, Jon
Mare, Olindo (will possibly be re-signed)
CB/DB
Jennings, Kelly (most likely won't be re-signed)
Lewis, Roy
Trufant, Marcus (likely contract restructure)
S
Babineaux, Jordan (most likely won't be re-signed)
Milloy, Lawyer (most likely won't be re-signed, or will retire)
LB
Curry, Aaron
Hawthorne, David
Herring, Will (most likely won't be re-signed)
Hill, Leroy (most likely won't be re-signed)
Tatupu, Lofa (likely contract restructure in 2011 or 2012)
Overall it's pretty interesting to see all this in the same spot. Most of the 27 'Pre-Carroll' players have some sort of caveat next to their name as well. Trufant and Tatupu are candidates for contract restructuring. Brandon Mebane, Chris Spencer, Matt Hasselbeck, Lawyer Milloy, Kelly Jennings, and Sean Locklear - all starters in 2010, will most probably not be back, further completing this entire roster makeover.
If many or all of the current free agent "Pre-Carroll" players do in fact leave, we'd be looking at 14 or 15 guys left from the Seahawks' roster as it stood in January 2010, just before Pete Carroll was hired. Wow. To me, this is as close to a 'rebuild' as you're going to see in the modern NFL.
