When Al Jefferson joined the Jazz, Utah point guard Deron Williams declared he was going to make his new teammate an All-Star.

Since Williams was traded, however, Jefferson has been playing his best basketball of the season.

In Monday night's 107-102 loss to the Celtics, Jefferson finished with 28 points, 19 rebounds and two blocked shots.

Over the past six games, Jefferson is averaging 27.2 points and 11 rebounds.

"He's doing a great job of reading the offense," said Jazz coach Tyrone Corbin.

"He's coming off tight and getting the ball close to the basket, where he can catch it and make something happen real quick."

Since he was 2 of 14 from the field in the Jazz's first game without Williams, Jefferson has made 70 of 121 field-goal attempts.

"[I'm] just getting more comfortable with this offense, and my teammates do a great job of getting me the ball," Jefferson said.

"I think this the first time I'm actually feeling like my old self since the injury. Just doing what I know I can do best."

Jefferson suffered a torn ACL in 2008-09, when he played in Minnesota.

In Williams-less Utah, Jefferson and Paul Millsap have emerged as the Jazz's primary options on offense.
