As star after star migrated from the Eastern Conference to the West this summer, the lesser of the NBA's divisions got so watered down that some spice was badly needed.

Kyrie Irving delivered.

The mercurial guard stunned the rest of the league by requesting a trade away from LeBron James and the Cavaliers and the annual trip to the NBA Finals that comes with James. In subsequent interviews since he was traded to the Celtics, Irving has done little to smooth things over with the game's best player or the franchise that drafted him No. 1 overall in 2011.

"It's just really between two men," Irving said last month when asked if he planned to reach out to James to clear the air. "If it happens or not, I'm pretty sure you guys won't know about it."

James didn't hide his disappointment in Irving's decision after teaming with him to go to the last three finals and win a championship two years ago.

"I tried to give him everything and give him as much of the DNA as I could," he said. "At some point, when he was ready to take over the keys, I was ready to give them to him. So, the only thing I'm upset about is he took a lot of the DNA and a lot of the blueprint to Boston."

James wasn't the only one upset by the deal.

Isaiah Thomas was deeply wounded by Boston's decision to trade him after an emotional and dominant season, setting the stage for a tense fight for conference supremacy.

"It definitely caught me off guard, but it also woke me up," Thomas said. "It made me realize that this is a business and anybody other than probably LeBron James or Kevin Durant or those type of guys can be traded."

This level of drama and intrigue is needed in a conference that lost Jimmy Butler, Carmelo Anthony, Paul George, Paul Millsap and Jeff Teague over the summer.

A look at the East, in predicted order of finish:

PLAYOFF BOUND

1. Cleveland — Death, taxes and LeBron in the finals.

2. Boston — The biggest question may be how will they account for the loss of Avery Bradley and Jae Crowder on defense.

3. Washington — John Wall and Bradley Beal are ready for prime time. Now they have to get the rest of the team to follow them.

4. Toronto — Perpetually overlooked around this time of year, Kyle Lowry and DeMar DeRozan refuse to give in. Adding C.J. Miles was an underrated score. If they can breathe a little more movement into their offense, they'll be in the mix again.

5. Miami — Here's betting the second half of last season (30-11) was a lot closer to what the Heat actually are than the first half (11-30) was. A team that plays as hard as they do could climb even higher in the wide-open East.

6. Milwaukee — Giannis Antetokounmpo — aka the Greek Freak — seems destined for MVP consideration in the very near future. Jabari Parker's recovery may keep him out until February, which could hinder the Bucks' climb up the ladder this season.

7. Charlotte — Here is where it starts to get really tricky. This is a vote of confidence in coach Steve Clifford's ability to get more out of Dwight Howard than anyone since Stan Van Gundy.

8. Philadelphia — If Joel Embiid is somehow able to stay healthy for 60 games or more, veterans like J.J. Redick and Amir Johnson should be able to usher these kids into the postseason.

IN THE MIX

1. Detroit — Getting Bradley from the Celtics is a nice fit for Van Gundy. The bigger issue will be getting a team that at times seemed fractured and miserable last season on to the same page. That starts with Reggie Jackson and Andre Drummond.

2. Orlando — Someone has to be 10th. Adding Jonathan Isaac's defensive instincts to the roster is a plus, but it remains an imbalanced team light on shooters and long on big men in a league that is getting smaller by the day.

FACING LONG ODDS

1. New York — New GM Scott Perry is boldly trying to go where few Knicks executives have gone — to Rebuilding Road. Now that Carmelo Anthony and Phil Jackson are gone, it's Kristaps Porzingis and a bunch of unknowns trying to turn the corner.

2. Brooklyn — A year after posting the worst record in the NBA, the Nets should be ... a little bit better. Coach Kenny Atkinson has more to work with in DeMarre Carroll, DeAngelo Russell and Allen Crabbe.

3. Indiana — Everyone knew Paul George was on his way out. That made deal-making difficult for GM Kevin Pritchard, and it showed in the return he got for one of the best players in the league. Now Myles Turner will have to step into the void, which is a big one.

4. Atlanta — That 60-win season seems longer than two years ago. New GM Travis Schlenk arrives from the Warriors, and it is going to take him some time to tear things down and build them back up.

5. Chicago — Likely opening night starting five: Jerian Grant, Justin Holiday, Paul Zipser, Nikola Mirotic and Robin Lopez. Enough said.

WHAT TO KNOW

LEBRON'S FUTURE: There are more than just whispers that James will leave the Cavaliers after this season, with the Lakers and Clippers as two potential suitors. James has said he intends to finish his career in Cleveland, but that doesn't figure to quiet the questions until he signs a new contract next summer.

SIMMONS DEBUTS: 76ers G/F Ben Simmons, last year's No. 1 overall pick, missed the entire season with a foot injury. He is ready to go this year, giving the Sixers even more hope that all the pain of the last few years is finally behind them.

HAYWARD'S IMPACT: Gordon Hayward was one of the few stars to leave the Western Conference for the East this summer. How quickly he assimilates with Irving and Al Horford will directly impact Boston's ability to unseat the Cavs.

HOT SEAT: In a volatile industry, the NBA went an entire season without a coaching change for the first time since 1963-64. The odds of that remarkable stretch of stability holding until the start of next season are remarkably small. Van Gundy, Clifford, New York's Jeff Hornacek and Indiana's Nate McMillan enter the season under scrutiny.
