Ok, OB1 out of loyalty to Qui-gon is determined to train Anakin(in ANH he says he thought he could do a better job, anyhoo). Of course the council reluctantly agrees to let Anakin b trained. But why did they let OB1 train him? He was still a Padawan. Barely out of his training, & even if Qui-Gon thought he was ready for the trials, that didn't mean he was ready to teach someone. So, why didn't the Council then say, ok, Anakin will b trained, but we will have a more experienced Knight or Master train him.
