I thought that after the very first fight. I haven't watched since episode three, but it sounds like nothing has changed in that regard. Being a great athlete does not necessitate great coaching ability - as Jon Jones as reminded us.
Yup, it speaks volumes that Luke Barnatt is going out to train with Chael after the show is done. Jones is too young and self involved to be a good coach, he really couldn't give two shits about anything but his own image.
Sonnen is one of the nicest guys in the sport, along with having good natural coaching instincts.
