"I'm pissed." This is how Miami Heat president Pat Riley began his end-of-the-season news conference on Thursday. (Watch video below to see how pissed Riley was.)

But this was just the beginning of a litany of rant during the 55-minute session who brought together the three star players (LeBron James, Chris Bosh and Dwayne Wade) in one powerhouse team that has claimed the NBA Finals for the past two years, except this year after the San Antonio Spurs devastated them with a 4-1 series win.

Riley noted that Miami Heat do not need to rebuild, instead it needs to retool. "And that's what we're going to do," AP-Sports quoted him as saying.

USA Today reported that Riley challenged Heat star James to stay with Bosh and Wade. He, however, recognized the fact that James can do whatever he wants to and should be given the time to get away from basketball in order to carefully consider his options.

The team president also noted that it is a also dream for the team to add another star to their Big Three which according to previous reports could be New York Knicks' Carmelo Anthony. But Riley said he does not "harbor on that thought", saying they are thinking about other things and strategies.

Hitting on the members of the media and also the fans, Riley said that "everybody needs to get a grip."

"Media, Heat players, organization, you know, all of our fans. You've got to get a grip on greatness, and on teams," he added.

"They didn't run. They didn't win. You've got to deal with it. You've got to come back" was Riley's reaction on the recent loss of his team to the San Antonio Spurs.

He explained that stuff like this is hard and that staying together is harder. Riley also challenged his players if they have the guts to still stay and fight with the team.

"We have a chance to do something significant, but losing is just as much a part of it as winning is... and when you're a team, you deal with it," he added in the press conference.

He also stressed on the team's goal which is to look inward after the finals game just like what the San Antonio Spurs did in 2013, USA Today reported. Riley also mentioned that after the Heat's loss in this year's finals, he drank Johnnie Walker Blue with his wife while listening to James Ingram's Just Once song which opens with the line "I did my best but I guess my best wasn't good enough."
