Cleveland Cavaliers owner Dan Gilbert had a long night Monday, but the wait for rest was well worth it.

At 1:48 a.m., Gilbert expressed excitement as the Cavaliers' front office and all-star point guard Kyrie Irving reached an agreement on a maximum contract extension worth $90 million over five years.

"Looking forward to the next 6 years of @KyrieIrving in CLE," Gilbert tweeted. "Just shook hands &intend to sign on the 10th. Can't be more excited about @cavs..."

Irving expressed the same excitement as Gilbert did.

"I'm here for the long haul Cleveland!!! and I'm ecstatic!!" Irving tweeted. "Super excited and blessed to be here and a part of something special. #ClevelandKID."

With a year already remaining on his rookie contract, Irving will be in the wine and gold for the next six seasons.

Irving played in 71 games this past season, the most of any year in his three with the Cavaliers. He scored 1,478 points, an average of 20.8 per game, handed out 433 assists and hit field goals at a 43 percent clip.

However, Irving's shooting percentage and 35.8 three-point percentage were the lowest of his career, and his relationship with fellow guard Dion Waiters was called into question throughout the year.

"In terms of their fit on the court, I think you've seen flashes of them being very, very good together," Cavaliers general manager David Griffin said in his post-season press conference. "What you've seen is they're part of some of our very best lineups together, but those lineups require spacing and shooting to play with them.

"They're two ball-dominant, drive-and-kick creators, and that requires an open floor, and it requires shooting. We need more of those things. It also requires the basketball IQ to play off of those players. This is not something that's done in a vacuum. It's not about their fit. It's about our fit."

Although his percentages and scoring average were down this year, Irving was the NBA All-Star Game Most Valuable Player and showed signs of improvement in the leadership department, according to Griffin.

"I think he's made the strides that he needs to make in terms of his openness to realizing his role as a leader," Griffin said. "He's 22 years old. We have to have very realistic expectations for him. What he's done a very good job of is opening himself up to the team and to trusting more.

"You've seen how good he can be when he plays with USA Basketball and when he trusts everyone around him. That's a difficult process when you're a young kid, and I feel like he's made really good strides in that area, and I know our staff does as well."
