Garnett and Jeff Green is easy.
The 3rd one isn't. GG gives you a shooter / slasher. Gamble a hustle forward.
None of them are ball-handlers. None of them allow you to go big with a 2nd big next to KG in a super-sized lineup; Artis is too old unfortunately.
I guess Gamble is the most accomplished but I don't really consider him much different than Adrian Griffin; Gamble was just lucky enough to play with better players like Bird to make him look good.
I'll go with Gamble. Post up the midget. KG and two forwards; post up the midget on the opposing team. Play tough D.
