One of the biggest surprises of the NBA offseason so far was when the Indiana Pacers sent star forward Paul George to the Oklahoma City Thunder in exchange for Victor Oladipo and Domantas Sabonis.

It was especially shocking because the Cleveland Cavaliers had shown heavy interest in PG-13 and were seemingly on the brink of finalizing a trade before Indiana general manager Kevin Pritchard got cold feet and nixed the deal.

Cleveland owner Dan Gilbert is understandably still upset about the Pacers' actions, and voiced his displeasure on Wednesday.

Gilbert spoke to reporters during a press conference introducing new Cavaliers general manager Koby Altman, but was asked about the failed Paul George trade. He didn't say much on the matter, but did offer a pointed criticism of the Pacers (via ESPN.com):

"I will say that Indiana could've done better than it did," Gilbert said.

Gilbert's opinion is shared by many around the league, who think the package of Sabonis and Oladipo was not nearly worth a player of George's talent level.

Altman wouldn't comment on the Paul George trade specifically, but did add during his first press conference that he was actively exploring a number of potential deals on the night of the NBA Draft and throughout the offseason:

"That's been well-publicized," Altman said of the George deal that fell through. "I don't want to talk about that. What's interesting is, over the course of the NBA draft, there's 60 picks. In the first round, there's five minutes between picks. I probably made 200 phone calls that night, and none of that gets publicized. We're actively trying to get better and discover what opportunities that are out there. It's the ones that sort of don't make it to the media that are the ones you're more crushed about.

"So, we're very active during that time. Also, we're aggressive in trying to figure out how can we get better for this organization. So, I'm not going to talk about that specific trade, but know that we were active during that time and every team in the NBA was active during that time, trying to help their respective franchises."

The biggest move the Cavs have made this offseason is signing Derrick Rose to a one-year deal, but Altman may soon have his hands full, as star point guard Kyrie Irving has recently made it known that he wants out of Cleveland.

How Altman handles the growing discontent in the Cavaliers' locker room remains to be seen, but his summer will certainly be interesting.
