Pepe, I'm glad you made that point about how Cochran is useful to Coach and he does have incentive to humor him. I thought about that after I made my recent post here, and I agree.I just don't think that Cochran gets to singlehandedly dictate the vote out. As we have seen, Albert and Sophie (and Brandon) have strong opinions. Albert is very physical, and I think it's safe to say that he sees challenge monsters as the bigger threats.
Even though Dawn did win a challenge, all the men outlasted her, so she is stronger than Whitney but not Ozzy or Jim. Also, older women tend to get discounted until they prove themselves to have "Jane" level of toughness.
Jim is going to be a target because he is both clever, a talker, and strong.
With Ozzy, it is too obvious to need a mention, but with respect to RI strategy, I would think if they consider it, better to send Ozzy early on, while there are still adept challenge players who could send him to the jury. The sooner he goes, the less likely he is to make it all the way.
Ozzy, Jim, Whitney, Dawn ... varied only if immunity wins force a change-up.
I think that once the first three are gone, Cochran could possibly try to ally with Dawn and try to crack Upolu. I guess it depends on how well Coach strokes his Shambo's ego and whether or not Cochran feels secure. Secure may not exist in Cochran's lexicon other than as an antonym to how he feels.
