Question: why plo koon is the best?
Answer: Who was the greatest Jedi ever and why was it Plo Koon? Because Plo Koon was calm, peaceful and serene, which is hard to do when you're from a race that has a tendency to see everything in black and white. Plo Koon cared for his troops and the other Jedi; he cared for Little Ahsoka.
