Even if the Knicks were exclusively looking for a versatile defensive player who could help the team return to what worked for a long time, however, Isaac Okoro would be an excellent choice.
Okoro has a long structure, impressive athleticism and willpower to stay focused and engaged in defense even through the worst offensive spells.
His positive side is that of an All-Defense player in the NBA, however, and it is something that should really intrigue the Knicks.
With Okoro and Mitchell Robinson on the floor together, the Knicks would have two players able to block their respective positions. More importantly: New York would have two versatile defenders who can swap and challenge almost anyone on the floor in a pinch.
