This trade will work out for both parties, though it's unlikely that the Los Angeles Clippers will look to make a move with their current success unless it's a deal that is clearly favorable for them.
Even though the Clippers look like the most balanced team in the NBA, they still lack a reliable post scorer who can get points on the interior at will. Blake Griffin has an improving post game, but his work down low is far from brilliant.
Jefferson would be the last missing piece to the Clippers if they were willing to accept his strengths and weaknesses as well. With their depth, he certainly won't hurt them as significantly on defense as one might think.
Mo Williams would fit right in after reuniting with the Clippers and could substitute as the backup point guard once again.
On the other hand, the Jazz get two quality young players in Eric Bledsoe and DeAndre Jordan. Bledsoe would be a perfect match for a team with a bunch of young, talented players looking to succeed in the near future. Although learning from Chris Paul and Chauncey Billups has drastically helped Bledsoe, he's a capable starting point guard in this league, and he's too talented to be buried on a deep Clippers bench.
Jordan would probably have to fight for minutes with two of the current young bigs on the Jazz—Derrick Favors and Enes Kanter.
However, Jordan still has a lot of room to grow as well, and it's not like he was averaging 40 minutes per game as a starter for the Clippers. He's actually just playing 24.5 minutes a contest and won't stunt the development of Favors or Kanter that much.
Caron Butler can provide some veteran leadership and shooting to a group of young players who won't have many experienced voices in the locker room if Millsap and Jefferson do leave.
