I'm still on board for adding a legit, physical 7-foot center. I'm not sold on Amir being a full-time option at the 5, and I view KO and Zeller as backups.
I have to confess that I am not a fan of Sullinger, and hope that Ainge manages to recoup some value for him this offseason. Would like to see Jerebko and Amir soak up the majority of the minutes at the 4.
The thing is, I don't see how you could play Amir and Koufos together very often at all. Amir and Zeller will mostly operate in a timeshare playing next Sullinger, Olynyk, and Jerebko. I doubt they'll be on the floor together very much.
Koufos is just not a need at this point. I agree that Zeller is a backup, but Koufos is probably not your ideal starting center, either. He too would probably play at most 24-26 minutes a game.
What about the Amir-Koufos tandem worries you? Is it Amir's ability to guard out to the perimeter? I think he has enough of a face-up game to keep the lanes open and give Koufos enough room to operate down low.
I think Amir Johnson's jump-shot is getting way too much credit on this forum over the last few days.
The stats being bandied about were FG% but do not mention volume:
10-16 feet = 38.5%
16-23 feet = 45.8%
3 Pointers = 40.4%
Here is the volume
10-16 feet = 5 made jump shots
16-23 feet = 11 made jump shots
3 Pointers = 19 made jump-shots
That is 16 two point jump-shots made in 75 games played.
35 jump-shots total outside of 10 feet. That is basically one every 2nd game.
Amir Johnson has done better in previous seasons and hit closer to 1 jump shot a game ... but this is not the type of threat that opponents worry about. Amir is the guy that opponents want to shoot the ball. That try to force him to shoot those shots. That leave him open to take those shots. But Amir rarely takes those shots because he does not think he can make enough of them. The shooting percentages are deceiving. Amir Johnson is one of the worst jump-shooting starting PFs in the league.
Amir Johnson is a (highly efficient and effective) garbage man. He takes the occasional jump-shot but that is not his game. And as you can see by the volume of jump-shots he makes, that is why Amir maintains such a high FG% (57% last year) because the vast majority of his shots are close to the basket (464 out of 519 FGAs within 10 feet of rim).
