Yeah, personally, unless Asik really REALLY wants out, I'd just run with this current group, add another wing vet probably.
I figure at least one of Dmo / Jones or even Smith takes a step forward.
To me, at least as a starting unit, Jones seems more reasonable, as he's the one who can do almost everything, and his primary weakness (shooting) is going to be mostly hidden because you know... he'll get no touches.
Dmo seem like the perfect small ball killer , his problem is really that he can't defend big PF in the paint, but against small ball lineup this isn't a issue, and smaller guys aren't going to stop him in the post. while he's fast enough to close out on perimeter.
Smith is a nice guy when you want to just go crazy with pick and roll. I hope he make some stride defensively,
And you have Asik , making this almost a fool proof lineup for 48 min, and in certain matchup situations just go stupid big and destroy them inside, the good thing about this is that, for guys their size, Asik and Dwight are both surprisingly fast (dwight especially , is really fast enough to play PF.), we were having Asik chasing Dirk and LMA this past season.
