Asik is to old(29) i feel like we can get expiring contract(s) and or a young so so player that has potential, or a draft pick.
First of all Asik I believe is 27 and only 2 months older than Green. Green relies on his athleticism much more so it would be logical to assume that Green's play would decline faster than Asik's.
Also SF is the easiest position to fill in the NBA. SF is a another way to say under skilled SG or undersized PF. C on the other hand is the hardest position to fill.
On top of that, Asik I think complements Sullinger perfectly defensively and won't prohibit anything he does offensively (although I don't think he will enhance it). This trade would be a no brainer.
These it's more talent at Sf than at most other positions - all the more reason why you HAVE to have a solid SF because otherwise you are behind.
C is a position lacking talent, so of you don't have a great center it didn't really matter much (see - Miami).
Umm, no. If you have LeBron, you don't need a center, because LeBron is in a class of player by himself. Miami is great because they have LeBron, end of story.
That center is a lacking position is why even someone of Asik's quality (and he is quality, offensive limitations and all) gives your team a relative advantage, because it means your opponent needs to have an advantage somewhere else to make up for it (see, again: LeBron). Green is a good player. But against almost all teams he doesn't give you an advantage, although he doesn't put you at a disadvantage either. Which is fine, but the reason he doesn't give you either an advantage or disadvantage is because his position is so deep, and most teams have a player near Jeff Green's level at his position. Some teams even have backups at Green's position that are near his level. In fact, you could argue that Boston is one of those teams with Wallace.
3/4 hybrids, and straight-up 3's, are plentiful in the NBA right now. If Jeff Green were traded for Omer Asik, Danny would have a new small forward by the beginning of the season that would make you forget Jeff Green. In the meantime, you'd have a little more Gerald Wallace, and maybe some weird lineups with Bass or Brooks at that position. And you'd have a real center to alter shots and grab rebounds and anchor your defense, and it would be a pretty decent team, because we've seen this current team get crushed by teams with real post presences. And I bet we'll see more of the same tonight.
