Most of the moves in 2018 NBA free agency have been made, meaning teams are almost set for the new season which begins later this year.

Some of the biggest moves of the free agency include LeBron James signing with the Los Angeles Lakers, Paul George signing a new deal with the Oklahoma City Thunder, and DeMarcus Cousins joining the Golden State Warriors.

While some teams may have missed out some top players this offseason, the good news is they'll only have to wait a year before they get another opportunity to sign some top free agents.

Anyone of the seven players below has the potential to change the fortune of any franchise in the NBA next year if they pursued them. Four of the seven players on this list are former NBA Champions. One is even a former MVP winner.

With that, here are seven of the biggest names that could be available for teams to sign in free agency in 2019.

Kevin Durant

The Warriors star has made quite the impact at the franchise since joining two years ago, but he still could be a free agent next summer.

Durant has a player-option in 2019 and, if he chooses to exercise it, the two-time NBA Champion and MVP winner would be the most coveted free agent on the market. He could go to any team he likes.

Kyrie Irving

Irving only moved to the Boston Celtics a year ago, but he could be a free agent in 2019. This could allow him to move to a market he likes should he feel uncomfortable in Boston two years on moving there via trade.

Like Durant, the point guard would have several teams after him since he is one of the best in his position in the league, and he has plenty of postseason knowledge he can bring to any new team he lands at.

Jimmy Butler

Another point guard that could be available next summer is Butler, who is expected to turn down his player option for the 2019-20 season to get more money before he hits 30.

The 28-year-old has improved the Minnesota Timberwolves ever since his arrival last year, and he's bound to do the same for any franchise he signs for next offseason should he become a free agent, and at a much cheaper rate than both Durant and Irving.

Kristaps Porzingis 

Chances are Porzingis likely won't be a restricted free agent in 2019 because he’ll probably sign a max early extension before the October 2018 deadline. If he doesn't though, the New York Knicks will secure him with a max offer sheet.

However, should the unthinkable happens, a lot of teams would be interested in the 22-year-old, as he is one of the most promising young players in the NBA today. A lot of teams would love to build a franchise around him, but it might be a longshot for them to acquire them.

Klay Thompson

The Warriors will do everything they can in order to keep Thompson and their super team together. However, if Durant is staying put too, it would likely mean Thompson will have to accept a deal much smaller than what he deserves.

If Klay wants a max deal, his time in Golden State would likely be over. There are plenty of other teams that would be willing to pay for the three-time NBA Champion to join their franchise.

Karl-Anthony Towns

Like Porzingis, Towns likely won't be a restricted free agent in 2019 because he’ll probably sign a max early extension before the October 2018 deadline. Minnesota won't want to see him leave either, especially if Butler goes.

If he doesn't though, the T-wolves will secure him with a max offer sheet. Besides Minnesota, the chances are slim for anyone trying to sign Towns next summer, but he might be available.

Kawhi Leonard

Leonard might have damaged his chances of getting his desired contract with his attitude over the past year, but that should all change over he hits the court for the Toronto Raptors following his trade from the San Antonio Spurs.

He does have a player option for 2019-20, so Toronto could convince him to stay, but if that desire for Los Angeles, they as well as the rest of the teams in the NBA might not stand a chance.
