I say the GM of the year is Jerry West. He might havent did any really big trades, but if you look at what he did compared to last year's roster then u will know. Here is a recap.
Pau Gasol
Mike Miller
Jason Williams
Lorenzen Wright
Wesley Person
Shane Battier
Stromile Swift
Mike Batiste
Earl Watson
Michael Dickerson
Chris Owens
Brevin Knight
Ryan Humphrey
Robert Archibald
Cezary Trybanski
Now after signing James Posey who has been one of the top players for the Grizzlies during the off-seaosn. Then trading Trybanski, Archibald and Brevin Knight for Bo Outlaw who is a big part of the 2nd unit and Jake Tskalidis who plays against players like Shaq. After that, he traded Person to Portland for Bonzi which really gave us some more depth. Batiste and Owens we're let go and Michael Dickerson retired and we will get the money from him next year. He also drafted Troy Bell and Dahntay Jones and he still isnt finish trading this year IMO because he is still searching for one more deal. If you look at our roster now and the roster from last year you will know he has to be the GM of the year. The reason why Lakers shouldnt have the GM of the year is because the only reason they came to LA was to win a championship. The Twolves shouldnt have a GM of the year because they actually had a superstar to work with in KG. Jerry West made some of the most unordinary signings and trades and turned the team into a playoff contending team.
