When Mikhail Prokhorov last saw his Nets play in person, back on Nov. 1 in the team’s win over the Heat in its home-opener, he said his new slogan for the Nets was “Aiming for Amazing.”

Assuming Prokhorov takes in his second Nets game Thursday in O2 Arena, where the Nets will face the Hawks, he’ll be watching a team that’s now “Aiming for Acceptable.”

Much has happened during the two-and-a-half months since the Nets’ Russian billionaire owner has seen them firsthand. The Nets have begun the most anticipated season in franchise history by turning it into the most tumultuous one.

There was the Jason Kidd-Lawrence Frank drama, which saw the deterioration of a longtime friendship and what was expected to be a successful partnership. Kidd also, of course, found himself in a bit of a sticky situation with the league office for spilling soda on the court, an incident that cost him $50,000.

There was the seemingly never-ending list of injuries from Brook Lopez to Deron Williams to Andrei Kirilenko. The loss of Kirilenko, in particular, set the team back from the start, and he has proved his value with the immediate impact he has had since returning to the lineup. And, of course, there have been a far bigger number of losses — and far fewer wins — than even the most pessimistic observers could have expected.

Prokhorov approved the blockbuster trade for Paul Pierce, Kevin Garnett and Jason Terry — and the combined $189 million bill in payroll and luxury-tax commitments that came with it — because he expected the Nets to be on the level of the Heat and Pacers in the Eastern Conference, as well as a legitimate challenger for an NBA title. Instead, the Nets have only moved back to within the playoff picture in the past week, and that’s only because the East is as weak as a conference has ever been.
