In what may be a preview of this year's Western Conference Finals, the top-seeded Phoenix Suns make the trip to San Francisco to take on the three seed Golden State Warriors on Wednesday.

While these are undoubtedly two of the premier teams in the West, the real story is about how the Suns have been in a class of their own this season, eight games clear of the second-best record in the league.

In the 21st century, only two teams have finished the regular season with a top-two ranking in both offensive efficiency and defensive efficiency: the 2014-15 Golden State Warriors, and the 2016-17 Golden State Warriors.

Both of those Warriors juggernauts went on to win the NBA Championship, and if the season were to end today, Phoenix would become the third team to achieve those marks.

Phoenix's net-rating – which illustrates how many more points a team is scoring than their opposition per 100 possessions – is plus 8.5, which is nearly two points clear of the second-placed Boston Celtics at plus 6.8.

The Suns have not just been the best team in basketball this season, they have been historically good in a way that compares the peak of the Warriors' run, and ranks better than any of LeBron James' Miami Heat teams, or the three-peat Los Angeles Lakers from 2000-02.

The Warriors, on the other hand, have been sputtering since Stephen Curry was sidelined with an injury that is expected to keep him out of action until the playoffs.

After three consecutive losses, can the Warriors pose any real threat to such a great Suns team? Stylistically, they may have some factors working in their favour, and as the saying goes, styles make fights.

These are two teams that play in similar ways. Both teams are bottom-five in percentage of their total points coming from the free throw line, both teams are top-five in percentage of two-point baskets coming from assists, and both are top-three in fewest blocked shots.

What this means is when these teams go inside to score, they are playing a finesse game focused around passing, movement, and creating open shots, as opposed to a bully-ball style which focuses on creating contact and forcing a way to the free throw line.

For a team like the Warriors that gives up free throws at the fifth-highest rate in the league, having a team that is willing to match their style and be a willing dance partner will hide some deficiencies and allow the home side to lean into what it does well.

Golden State also attempts the second-highest percentage of three-pointers – nearly 46 per cent of all of their shots come from long range – while Phoenix is way down at 27th in the league, taking 65 per cent of their shots from two-point range.

Despite that stat implying Phoenix is dominant in the paint, they actually are 16th in paint scoring, but third in mid-range scoring thanks to the efforts of Devin Booker and Chris Paul.

It is well-established at this point that mid-range jump shots are the least efficient shots in all of basketball, while an open three-pointer is the best shot a team can take other than a dunk, layup or free throw.

Phoenix has been great on a diet of difficult shots this season, but if the Warriors can get hot from three-point range at the volume they get them up, the Suns may simply lose the math equation.

PIVOTAL PERFORMERS

Phoenix Suns – Chris Paul

Of every player in the NBA this season averaging at least 20 minutes per appearance, only two – LaMarcus Aldridge and DeMar Derozan – score a higher percentage of their points from the mid-range than Paul.

As discussed, Phoenix will need to score consistently and efficiently from the mid-range to counter how many three-pointers the Warriors will get up, and Paul is at the center of that.

Add into the equation that Paul leads the league in assists per game, while coming in at second in steals per game, and it's clear why he is so important at both ends of the floor.

Golden State Warriors – Klay Thompson

Simply put, the Warriors need to get hot from long range to win this game, and few players in the history of basketball can get hotter than Klay Thompson.

Thompson holds the NBA record for most threes in a single game, hitting 14 of them against the Chicago Bulls in 2018, and has made at least nine in a game on 10 different occasions.

While he is still working himself back into full form after returning from a two-year absence this season, over his past 10 games Thompson is averaging 24 points per game and is hitting a strong 40 per cent of his long range attempts.

KEY BATTLES – Can the Warriors compete with the Suns' size?

Golden State have only one player on their roster taller than six-foot-nine Kevon Looney, and it is James Wiseman, who will not play a single game this season due to lingering injuries.

Suns center Deandre Ayton measures in at seven-foot-one, and less than a week ago he physically dominated All-Star center Karl-Anthony Towns en route to 35 points and 14 rebounds.

Towns is bigger than anyone Golden State can throw at Ayton, and while Looney is an above-average defender, basketball is a game where size matters, and the Warriors are small.

HEAD-TO-HEAD

These two sides met on three separate occasions in December, with Golden State winning twice.

Curry top-scored for the Warriors in both wins, while Ayton out-scored his season average in all three meetings.
