The Portland Trail Blazers have exercised their third-year options on Damian Lillaard, Meyers Leonard and Thomas Robinson.

Lillard, the sixth overall pick in the 2012 NBA Draft, averaged 19.0 points, 3.1 rebounds and 6.5 assists in his rookie campaign with the Trail Blazers. Only the fourth unanimous Kia NBA Rookie of the Year in league history and fourth Trail Blazer to win the award, Lillard finished last season as one of three rookies in NBA history with 1,500 points and 500 assists.

Leonard, the team’s 11th overall pick in last year’s draft, posted averages of 5.5 points and 3.7 rebounds on 54.5 percent shooting from the floor and 80.9 percent from the charity stripe in his first season with the Trail Blazers.

Robinson, entering his second season in the league, joined the Trail Blazers in a trade with the Houston Rockets on July 10, 2013 in exchange for the NBA rights to Kostas Papanikolaou and Marko Todorovic along with two future second round picks. In his rookie season, Robinson averaged 4.8 points, 4.1 rebounds and 15.1 minutes in 70 games with Sacramento (51 games) and Houston (19 games).

Terrel Harris has been waived by the Portland Trail Blazers, the team announced on Monday.

Harris was given a five-game suspension earlier in the offseason for violating the NBA anti-drug policy.

Harris has played for the Miami and New Orleans in the past two seasons.

Forbes' "Richest 400 Americans" includes 14 owners in the NBA, headlined by Paul Allen of the Portland Trail Blazers, who also owns the Seattle Seahawks.

The richest NBA owner is Orlando Magic owner Rich DeVos, who comes in at No. 60 on the list with a net worth of $6.8 billion.

There are 12 other NBA owners on the list, including Kroenke (Nuggets), Micky Arison (Heat, $5.9 billion), Dan Gilbert (Cavaliers, $3.9 billion), Charles Dolan (Knicks, $3.3 billion), Tom Gores (Pistons, $2.7 billion), Mark Cuban (Mavericks $2.5 billion), Josh Harris (Sixers, $2.5 billion), Robert Pera (Grizzlies, $1.95 billion), Herb Simon (Pacers, $1.95 billion), Donald Sterling (Clippers, $1.9 billion), Glen Taylor (Timberwolves, $1.7 billion) and Tom Benson (Pelicans).

The richest person involved in the sports world is Nike chairman Phil Knight.

The Portland Trail Blazers have signed rookie forward Richard Howell.

Howell, 22, averaged 12.7 points (51.8% FG, 63.3% FT), 10.9 rebounds, 1.7 assists and 31.6 minutes his senior 2012-13 season at North Carolina State. A First Team All-ACC selection last season, Howell ranks fifth all-time in school history with 1,055 rebounds.

He appeared in three games for the Denver Nuggets 2013 NBA Summer League entry in Las Vegas, averaging 1.7 points, 2.0 rebounds, 1.30 blocked shots and 10.7 minutes.

Damian Lillard believes LaMarcus Aldridge should start shooting more three-pointers, and he was asked in rapid-fire questions whether Aldridge actually will next season.

"Yeah, I do," Lillard said.

Aldridge attempted 14 three-pointers last season and 101 in his seven seasons.

When asked what C.J. McCollum will hate most about the NBA in a rapid fire format of questions, Damian Lillard answered: "The egos."

McCollum went 10th overall in the NBA draft to the Portland Trail Blazers.

Lillard has said this offseason that his already built relationship with McCollum should help the two mesh on the court.

Former North Carolina State standout Richard Howell has agreed to sign a partially guaranteed contract with the Portland Trail Blazers, his agent Joel Bell told RealGM.

Howell had been bought out from his French team and flew to the States to sign his new deal on Friday. Despite having 15 players under guaranteed deals, the Blazers are intrigued by Howell, the 6-foot-8 forward who averaged 12.7 points and 10.9 rebounds in his senior season at N.C. State.

After going undrafted in June, Howell played for the Denver Nuggets’ summer league team.

Howell, 22, impressed NBA teams in the pre-draft process and projects as an active, rugged presence inside.
