The balance of power in the Eastern Conference was shifted so forcefully at yesterday’s NBA trading deadline that the shockwaves were powerful enough to put a smile on Allen Iverson’s face.

“At first people weren’t talking about us getting to the Eastern Conference Finals, so it’s just a great feeling,” Iverson said. “I’m just looking forward to the rest of the season.”

The 76ers made a seismic splash in acquiring five-time All-Star Chris Webber in a blockbuster trade late Wednesday night. Philadelphia is buzzing because Webber is the best power forward to play in that city since Charles Barkley put the Spectrum on the map during the 1980’s.

“To tell you the truth . . . I’ve been looking forward to something like this for nine years,” a gleeful Iverson said prior to last night’s game against the Knicks. “I think my career is going to turn a corner.”

Webber is, without question, the most talented big man to play with Iverson, who was named the MVP of last weekend’s All-Star Game in Denver. Webber is also the most expensive sidekick Iverson has had, with three years and $62 million remaining on the seven-year, $127 million pact he signed with Sacramento in 2001.

“I think by him being on the court, just his presence, will make us a better basketball team regardless of how he plays,” Iverson said. “The sky’s the limit for what he will do for us. For me personally, it takes a lot of double teams away.

“I think we’re going to be real strong in the pick-and-roll game,” Iverson said. “He can shoot the ball so well.”

Averaging 21.3 points, 9.7 rebounds and 5.5 assists per game, Webber is a proven inside presence, a gifted scorer and even better passer, all traits that figure to open the floor for Iverson and company.

However, there are questions about Webber’s health after undergoing knee surgery in 2003.

“He may be the best passing big man in the NBA,” Sixers head coach Jim O’Brien said.

The No. 1 overall pick in 1993 out of Michigan, Webber was not at the Garden last night to face the Knicks.

He is, however, expected to play for the first time Saturday in Philly against – who else? – the Kings.

“All he wants to do is what he has to do to make this team better,” Iverson said.

“And prove a lot of people wrong that thought his game was over. Like I said, I’m just looking forward to it. I’m ecstatic.”
