Netero selects his team based on their abilities I think, not just how strong they are. So basically, Knov's and Morel's Nen abilities are useful and handy to the invasion, plus they are close friends who can work together. This isn't some simple shonen stuff where they just lump up the strongest characters and go for the explosive scenes rather than logical and well-paced fights.
