Defense doesn't win NBA championships, not by itself at least.

The true test of a contender is two-way balance, but that doesn't make for as catchy of a slogan.

What that oft-repeated coachspeak does remind us, though, is that even in an offense-crazed era, defense plays a major part in team success. That will put the three perimeter stoppers below on the draft radar of any club struggling to contain defensive leaks.

Top Perimeter Defenders

Isaac Okoro, SF/PF, Auburn

Want to know a tip for spotting an elite stopper? If a perimeter player emerges as a lottery prospect after a one-and-done season in which he didn't average 13 points or shoot 30 percent from three, there's a decent chance his bread gets buttered at basketball's less glamorous end.

That's the case for Okoro, who has plenty of room for offensive growth but could handle multiple NBA-level defensive assignments right now.

"Okoro, 6'6", 225 pounds, already possesses a convincing mix of power, quickness and focus for defense and guarding multiple positions," B/R's Jonathan Wasserman wrote. "He matched up with bigs, wings and guards all season, showing the ability to wall up inside and smother around the perimeter."

Okoro isn't a lost cause on offense. He's a savvy off-ball mover, a capable secondary playmaker and a good finisher around the basket (60.7 percent shooting inside the arc). But he's in the lottery discussion for his defense, and if Okoro ever nears his peak, he could be an annual All-Defensive honoree.

              

Devin Vassell, SF, Florida State

On first glance, Vassell can seemingly thank his three-point stroke for his surging draft stock. Clear 41 percent from three in two consecutive seasons as he did with the Seminoles, and modern NBA evaluators are sure to take notice.

While that steady stroke is part of his appeal, the real draw is his potentially dominant defense. The first three strengths on his scouting report from the Ringer's Kevin O'Connor all center around Vassell's defense.

It opens with the phrase, "elite team defender who will immediately help any NBA rotation." Words like disrupt and deter are used, along with the following three words sure to gain the affection of any coach, "never stops hustling." Finally, O'Connor dubbed Vassell an "impactful on-ball defender with the right blend of agility and length to defend guards and wings."

His per-40-minutes marks across two collegiate campaigns included 2.0 steals and 1.3 blocks. Even that might shortchange his defensive instincts and ability to maximize the impact of his athleticism.

                  

Josh Green, SG, Arizona

While Green didn't set the college hoops world ablaze during his lone season with the Wildcats, it's important to remember he shared the floor with two other potential first-rounders: Nico Mannion and Zeke Nnaji, both of whom got up more shots than Green.

That not only leaves Green with substantial room for improvement—think of all the Kentucky alumni who could only spread their wings after leaving the college's loaded program—it also means he could fully lean into the defensive end.

With turbo-charged explosiveness and lateral quickness, he can probably check the 1 through 3 spots most nights in the Association, and he can handle 4s in a pinch. His reflexes are razor-sharp, and he's a fast mover with his hips and his feet. He'll get his hands on the ball early and often as an on-ball best and an off-ball pest in passing lanes.

His offensive outlook is murky enough to bump him down the board on draft night, but his defense should keep him in the first round, and he'll be among the biggest steals if he realizes his chance to become elite at that end.
