2020 NBA draft prospects LaMelo Ball and Anthony Edwards have been the talk of the town. That makes sense, they're fun prospects with franchise-altering potential. 

But basketball teams are built on dirty work in the paint. And big men lead the way in that area, cleaning up the glass and bringing the physicality that championships are founded on.

Unlike some other drafts, this year's is incredibly sparse among the frontcourt, and only three players stand out as likely lottery picks: James Wiseman, Onyeka Okongwu and Precious Achiuwa—each a tier apart while still within the lottery.

Wiseman Offers Golden State's Clearest Return to Contention

Wiseman played just three games for Memphis this season before leaving the school after being handed a 12-game suspension by the NCAA over improper benefits. 

The sample size is small, but his numbers were not. At an imposing 7'1", Wiseman averaged 19.7 points (on 76.9 percent shooting), 10.7 rebounds and 3.0 blocks per game while averaging just 23 minutes of action. 

Although he didn't show off any range from three in the NCAA, that's not what Golden State needs him for, and he could still develop that aspect of his game. 

Wiseman's high school tape is reminiscent of a larger, healthier Harry Giles—routinely showing comfort handling the rock and knocking in jumpers, even off the stepback. 

A 70.4 percent rate from the line at Memphis is also enough to provide some confidence in Wiseman's shooting upside. His charity-stripe clip was well within striking distance of highly esteemed gunners like LaMelo Ball (72.3 percent) and Cole Anthony (75.0 percent). 

For 2020-21, Golden State's core group figures to be Stephen Curry, Klay Thompson, Andrew Wiggins and Draymond Green. What they're missing is a complementary big man who provides more size and athleticism than Kevon Looney. Wiseman is that and more, a perfect pick for a team with title hopes.


San Antonio Prioritizes BPA in Okongwu

It's a weird spot for a Spurs team in limbo at 27-36 this season. They have a group of young guards and a couple of bigs but don't have much impressive depth at the wing—even if rookie Keldon Johnson intrigues long-term.

San Antonio could gamble on a wing, but Okongwu simply possesses a higher floor than the prospects surrounding him. The 6'9" big plays larger than his height, understandably given his 7'1" wingspan.

In one season at USC, he averaged 16.2 points, 8.6 rebounds and 2.7 blocks per game. With a 61.6 percent clip from the field and 72.0 percent from the line, he seems poised to provide immediate rotation contributions at the next level.

LaMarcus Aldridge is 34 years old, and Jakob Poeltl didn't quite progress as some hoped he wouldhis field-goal and free-throw percentages have dropped for a third consecutive season, the latter to an abysmal 48.6 percent. Okongwu is a tough, useful basketball player, and San Antonio could use some stability in the paint during this forward-looking pivot.


Adding Achiuwa Cements New Orleans' Frontcourt

Both of New Orleans' more established big men, Derrick Favors and Jahlil Okafor, are unrestricted free agents this offseason. Neither engendered much faith during the season.

Their rookie, Jaxson Hayes, has eye-popping potential but is unreliable. The Pelicans have a young roster, and their window should fit Hayes' road to development, but they could use added depth in the frontcourt as they build.

Like Okongwu, Achiuwa is 6'9" but boasts a 7'2" wingspan and a record of dominance in just one college season. He averaged 15.8 points, 10.8 rebounds and 1.9 blocks per game. That paint presence is there, but he's a less traditional big with the shooting percentages to prove it. 

Bold shot selection left Achiuwa with a 49.3 percent rate from the field, 32.5 percent from deep (on 1.3 attempts per game) and 59.9 percent from the line. He can look lost out there, but the talent and instincts are still evident.

Given his upside and the uncertainty surrounding everyone else in his range, New Orleans could benefit from taking another shot on a big man with potential this offseason.
