Millsap and Jefferson never surfaced in trade rumors.
Utah had been open to moving Harris and reserve small forward C.J. Miles three weeks ago, Bell was on the market, and everyone from Josh Howard to Jamaal Tinsley recently factored into national trade rumors.
Many of the reported proposals lacked weight, though, and Utah spent much of its time during the buildup toward the deadline simply listening to pitches from other teams.
By holding on to Millsap and Jefferson, young Jazz big men Derrick Favors and Enes Kanter likely will continue to play reserve roles through at least the remainder of the season.
A Jazz team that fell 120-111 to Phoenix on the road Wednesday approached the trade deadline believing they're still competing for a spot in the Western Conference playoffs. As a result, the organization refused to make a deadline deal just for short-term gain.
Utah thinks its main moveable assets will be just as tradeable during the build-up to the 2012 draft or before the 2013 deadline, and the organization wanted to maintain its depth and continuity as it fights for a postseason spot this year.
While the Jazz weren't expected to make a blockbuster trade similar to the deal last year that sent All-Star guard Deron Williams to New Jersey, they were open to making minor changes. Nothing came to fruition, though, and the Jazz will move ahead with the same roster that's produced an up-and-down season thus far.
Utah started 12-7 and initially was one of the surprise teams in the league. But the Jazz have struggled since, going 8-15 and failing to build consistent momentum.
A team that has lost three of four plays host to Minnesota at 7 p.m. Thursday at EnergySolutions Arena.
The Jazz are tied with the Suns for 10th place in the Northwest Division and are only one game ahead of 13th-place Golden State, which visits ESA on Saturday.
Elsewhere, Orlando center Dwight Howard decided Thursday to stay with the Magic through the 2012-13 season by agreeing to waive his early-termination option.
