Yes, for one of those good SFs that are just laying around that no one is being specific about.
There are more good SF's out there than there are big men. So it makes sense to pick up a good lottery worthy big man, and trade for a SF. I can't be specific, because I haven't really looked into it, but I'm sure we could get someone.
Maybe Thaddeus Young? Great size and athletic ability, efficient, good rebounder, and young. Sixers need a good offensive big man. Not sure about his shooting, his first 3 years in the NBA he had decent 3pt %, but the last two years he has basically stopped shooting 3's. Sixers and Jazz have a good trading relationship, and the trade would make sense for both.
Sap for Young + 1st rounder. If we traded Jefferson we would have to add another contract because his doubles Young's.
Also, he averaged 41% from deep in college from 3. He cane get the stroke back if he is asked too.
