I originally was saying Bruce Bowen, but I love the versatility of Walter Herrmann. He big enough and active enough to get rebounds and play pesky long arm defense, but he's got a nice shooting touch from behind the arc. I just hope Detroit hasn't ruined his nba experience and forced him back to Argentina or Euro leagues.
My other signings that I'd make would be...
Resign Powe for 1 year to prove his knee hasn't ruined him.
Resign Marbury for more than the minimum, but more more than 2 over 2yrs
Resign BBD for 3-4 mil over 3 years(or wait for the first team to offer him something similar then match-I dont feel he's worth 5-6 yet)
Resign Mikki Moore for vet min. He's not the greatest backup, but he can play the 4 or 5 and can be our dependable 4/5th string big man.
TRADE Tony Allen for a better shooting versatile SG/SF like Thabo Sefolosha or packaged with Scal for Rasual Butler and Devin Brown
