While there are NBA teams with fluid head-coaching situations (Indiana Pacers, Washington Wizards and potentially the Milwaukee Bucks), only three jobs are up for grabs at the moment. Those teams are the Boston Celtics, Portland Trail Blazers, and Orlando Magic who have vacancies and are on the head-coaching search.

Here's a ranking of the three current NBA head coaching positions in terms of attractiveness.

3) Portland Trail Blazers

Yes, the opening with the best player on the three teams (Damian Lillard) is the least attractive of the head-coaching positions. How is that? There are two primary reasons for the knock on the Trail Blazers' job: Portland has a veteran core that's yet to win a Western Conference Finals game, and Lillard has an uncertain future with the organization.

Lillard, CJ McCollum, and Jusuf Nurkic have made a respectable competitor in the West in recent memory. They score at a high level, have continuity and continually make the playoffs. Simultaneously, they're doing little with what they have (they've had a consistent core with few moving pieces from a foundation standpoint).

It isn't easy to get a veteran core that has produced similar results for six years to have a breakthrough in a stacked conference suddenly. Plus, the Trail Blazers have minimal cap space at their disposal this offseason. They have to convince veterans to sign for the league minimum or close to it and find a diamond in the rough in the NBA Draft.

Has Lillard asked for a trade? He has not, but him going public about wanting Jason Kidd to replace Terry Stotts is bizarre, as was his Instagram post after the Trail Blazers were eliminated from the playoffs last week. Lillard is one of the sport's premier players and has been unable to win the West as the team's headman. The 30-year-old requesting a trade this offseason is a legitimate possibility.

The Trail Blazers aren't a bad coaching position. Rather it's a perplexing, repetitive situation for a coach to jump into.

2) Orlando Magic

The Magic were the 14th seed in the Eastern Conference this season. At the same time, that result paved the way for a team in competitive stagnation to kickstart a could-be smooth rebuild.

The Magic corralled two first-round draft picks from the Chicago Bulls as part of their return for star center Nikola Vucevic in March, meaning they have two potential top-10 draft selections this year (if the NBA lottery keeps their picks in place, Orlando selects third and eighth in the 2021 NBA Draft). They could have two immediate impact players coming their way.

By the rookies' side will be second-year guards Cole Anthony and RJ Hampton, who each showcased an ability to score at a plausible level, and Wendell Carter Jr., a capable inside player. Productive and improving young players like Jonathan Isaac and Markelle Fultz should return from injury next season, too. Keeping in mind the volatile nature of the bottom of the Eastern Conference playoff picture, the Magic could be back in the playoff mix in a couple of seasons with the right coach at the helm.

Of course, this is a rebuilding deal. No coach can realistically go into Orlando with the mindset of making the playoffs from the jump. Plus, it's difficult to firmly identify a true franchise player on their roster; that will have to come through drafting and developing.

There's a lot for a head coach to work with in Orlando. It's a matter of whether they can advance a young roster, which is easier said than done.

1) Boston Celtics

The Celtics are in a funky spot but can be salvaged, hence having the most attractive NBA head-coaching vacancy.

When healthy, Boston has a stout one-two punch in Jayson Tatum and Jaylen Brown. The homegrown players are proven scorers and defenders who have only improved with age. Big man Tristan Thompson and gritty guard Marcus Smart are by their side. Besides the proven commodities is a grouping of young players who have talent but need direction. That group includes Aaron Nesmith, Robert Williams III, Grant Williams, and Romeo Langford. Kemba Walker's future with the Celtics is a question mark.

A first-round departure is far from ideal for the Celtics, an inevitable outcome with or without Jaylen Brown based on the way they played towards the end of the regular season. That said, perspective is key, as the Celtics are a year removed from competing in the Eastern Conference Finals. They have a defensive-minded team with capable scorers and an abundance of playoff experience.

True, there are some heavyweights in the East. At the same time, some of those teams are up against the clock, as the Brooklyn Nets' big three can all become free agents next summer and the Philadelphia 76ers are a spiraling rumor mill. If the Celtics can get back on track, they're squarely in the conference mix. The next coach of the Celtics will be asked to get the organization back to being what they were designed and are expected to be: a contender.

Brad Stevens overseeing the operation is fascinating. Who he brings in to take the job will be interesting. Nonetheless, whoever takes the position has a compelling task ahead.
