I know most of the people in the forum will say Smart because he looks like he put more effort on D than Avery. But I think that post ASG, AB was superb defensively and had the same intensity as if it was 2013. I think that they both did a very good job on Irving and JR Smith in the playoffs.
These two players are both excellent defenders that deserve to be in any of the All Defensive Team ( I ain't saying that they must be there). But they are different because of their size and athleticism. So I'll make comparisons (in my opinion):
On-Ball Defense - AB wins here because he can defend at an high level elite point guards and smaller shooting guards and he does an helluva job in moving is feet quickly. Does an okay job against bigger guards. While, Marcus defend well smaller 1s as he moves his feet well but he might get burnt a bit but he can use his size in the post very well when 2s post him up (ask Harden).
Off-Ball Defense - I choose Smart simply because his IQ off-ball on D is one of the best in the league he understand where to position himself to defend effectively and he's active in the passive lanes. Bradley is good too, but he improved this season because I think Brad told him to focus on that.
Steals - About the same. People might think Smart because he gets more steals but I am sure that AB can get many steals but he focuses more on staying in front of his man.
Blocks - Not sure. I think they both are above average shot blockers for their size.
Screens - No doubt Marcus. This kid is so special in the way he battles through picks as bigs struggle to screen him effectively due to his powerful linebacker build. He rarely to go under the screens. AB is good at avoiding them due to his superior athleticism however he finds difficulty in going through the screens.
Well overall, I would like to say I prefer Marcus but not by much because they are both valuable defensively and they both combine to a very effective defensive duo (maybe the best defensive backcourt in the league?). The difference between the two is versatility. Marcus can defend up to 2.5 positions effectively (Pgs, SGs and some SFs) while AB can defend 1.5 effectively (Pgs and some SGs). Smart has the upside to be the next great perimeter defender and a perennial DPOY candidate a la Gary Payton while AB can be an very good perimeter defender who is a candidate for multiple NBA All Defensive Teams like Bruce Bowen.
Note: I am not saying they will be as good defensively as both guys.
So what's your opinion on this? Who is better? Why?
