So who is who? Which players do you prefer ahead of the others?
...........................
A - Nic Batum
B - Jeff Green
C - Jimmy Butler
D - Nick Young
E - Kawhi Leonard
Personally, I'd take Batum, Leonard, and Butler before Green or Young.
The point of all this is that I'd much prefer an all around player. Jeff Green, like Nick Young, does very little for a team other than score. This is what makes him so expendable. That's why Gerald Wallace does more to help this team win despite hardly scoring at all.
I don't see anything in the stats that would point to player C being a better all-around player than B or D. Also, I'm curious about what leads you to believe that Wallace is doing so much more to help the team win than Green.
Player C (Jimmy Butler) rebounds well for size and generates steals and blocks. He does so while not being a major part of the offense. He's a nice role player. Still, he's not so much farther ahead of Green than the other guys.
As for Nick Young's stat line, I think the main thing with him has always been how awful he is defensively. That said, when a player is scoring 17-20 points a game per 36, that suggests a very high usage rate, so when a player generates so few assists despite getting that many touches offensively, that points to an inability to add a lot of value in a team offense. He's also a very weak rebounder, though he's really more of a SG than a SF -- I included him mainly because he's the first guy that comes to mind when I think of players who basically score and don't do much else.
With Gerald Wallace, it's not so much about the stats. Obviously I don't want to play a guy 36 minutes a game who only scores 5 points. That said, what I see with Wallace is that he facilitates, rebounds, generates turnovers, and plays with a lot of energy. I think he is a valuable glue guy for the team. At this point in his career, he's only really effective doing it for 15-20 minutes a game, though.
Green, on the other hand, is a far more efficient scorer. But again, for a guy who has such a prominent role in the offense, he doesn't bring much else to the table. He doesn't make other players better, he doesn't generate extra possessions at all. So while that doesn't make Green a bad player, it does make him easily expendable, because you'd much rather have a guy who maybe doesn't take as many shots, but who does more all around to help you win.
Paul Pierce, of course, scored at a high level and did a lot of the other stuff, and when you needed him to step up a part of his game for the sake of the team (passing or rebounding), he could do it. But that's what made him a star.
I guess my overall point is, in the absence of an elite player like Pierce, or even just a truly elite scorer, give me somebody who makes a lot of hustle plays and moves the ball around well over the guy who has a nice scoring night every couple games. Players like Jeff Green make more sense coming off the bench.
