I think the trade will work out well for both teams.
First off, it is easier to insert a Korver into Utah's offense, then it is to mesh Giricek with the rest of the Sixers in the middle of a road trip.
And of course, the Sixers still have that all important cap space and a late first round bargaining chip.
I may be wrong, or overly optimistic, but I think the Sixers are better then their current record. Not that they're a contender, but they aren't quite as far away as it may appear. They have a shot at making the playoffs with the team they have. Based on the team stats they are at 18, only 2 spots out. And, they have been improving and developing a personality and identity as a team.
Korver is a very very good outside shooter, and free throw shooter as well- (Isn't it always that way?) He also has a quick release and is effective in a catch and shoot. But defensively, he is a liability, and he isn't a rebounder and isn't effective at blocking out his man.
He will help Utah more than the Sixers. In Phila. he wasn't consistent enough as a shooter, sometimes he was hot, more often, it seemed - not. With the Jazz he won't be the second or first option, but the third and with less pressure and more open looks, he should help the Jazz more.
Phila. has an abundance of people who can play at that spot, and may find that another player will help them in ways that they need more than they needed Korver.
