Battle of the terrible teachers

While their abilities as teachers were excellent, the results they had, were, shall we say, terrible for the Jedi:
Traya v Obi-Wan v Vodo-Siosk Baas.

so what are you asking, which student did more damage to the jedi/republic, or who would win in a fight?

If it is who did more damage to the jedi, then Obi-Wan's padawan wins here.

If it is who would win in a fight, then it is between Traya and Vodo, personally I think Vodo, he was like Yoda, hundreds of years old etc.

I would say Obi. He trained Anikan and Luke and they turned out to be great warriors. Thats gotta count for something.

In a fight.

obi screwed up the most
