It's that 3rd team that strikes me as the most off. Conley's a nice ball-hawk, but he's too small too make much of an impact. Rondo's length alone makes him a more effective defensive player, and there's other guys I'd prefer there too: Rose, Westbrook and Lowry come to mind; then there are bench guys like Eric Bledsoe and Iman Shumpert that can make a big impact.
Ronnie Brewer's nice but there are guys I like better defensively at the 2: D-Wade for one, not the most dedicated on-ball guy but a big defensive presence with his ball-hawking, rebounding and shot-blocking. Thabo Sefalosha and Paul George are more imposing defenders as well.
Grant Hill over Shawn Marion, Paul Pierce, Shane Battier, LRMAM, Gerald Wallace, even Artest... I just don't see it. I think Hill's just serviceable at this point in his career. Not enough quickness left.
I'd take Omer Asik over Ibaka too.
