I'm still deciding whether I think it's a risky but smart move, or just dumb. ozzy's very obviously playing this game emotionally, so I don't fully trust his decision making, but here's why I think it makes some sense.
you have to assume the merge is coming up. from a production standpoint, merging at 12 is much better than 10. if the teams are even (6-6), then someone has to switch (or let it go to a tie, which someone usually doesn't want to happen), which is good for the game. if the sides are uneven 7-5 or worse, then the more people the larger tribe has, the higher the chance that a small minority will realize their place in the pecking order and be willing to switch when the time is good. with a 10 person merge, 5 or 6 can more easily stick together longer.
so that said, it's a pretty safe assumption that they're going to merge. so knowing that, ozzy has to win 1 competition against christine. she's done very well and certainly they could have a competition where his athletic skills are mitigated, but I'd be willing to bet it's some type of endurance competition. anything outside of one that benefits being smaller (like some of the ones where you have to standing on smaller pieces of wood that benefit smaller footed people), he should have a distinct advantage.
so based on those two assumptions, he's got, let's say a 50% chance of coming back in the game immediately (and an additional percentage of getting back in the game if he has to win a few redemption island challenges). so assuming he comes back in the game, they'd have 6, and then with christine wanting nothing to do with her old tribe, they'd legitimately have 7 members and could obliterate the other tribe (if they wanted, I could see Jim and Cochran making deals down the road if it benefited them).
if they vote cochran out to redemption island, let's just say he has a much smaller chance of returning. so at best, you'd have at best, 6 on 6 with no guarantee that someone wouldn't switch over.
so essentially, they're taking a chance to regain control of the game, which I think is VERY unlikely if they just sent in cochran. Again, it relies on the fact that the merge is coming up next, but as i mentioned, I think that's a safe assumption. and if it's not until 10, then it really doesn't matter, because they'll probably still end up with a numbers disadvantage, but with less members and based on how solid the other tribe looks right now, they might be dumb enough to actually stick together like rob's tribe last year (in fact, that's probably another thing they have to figure into things...if coach's tribe is as solid as they seem right now, then you have to figure your chances of bringing someone over from their tribe are even lower).
also, the whole thing works because ozzy is volunteering, as opposed to it being put on him. that presumably guarantees that he comes back and has no problem rejoining the tribe. if cochran gets voted out and comes back, I don't think he's so happy about joining back up with them.
lots of different scenarios can play out, and it very well could end up not working for them. but it does give them a better chance at regaining the numbers. the question is, whether that's better for some of the members of their tribe or if they might not be better off going in with a numbers disadvantage and trying to find some holes in coach's alliance. but to me, that's an even poorer bet.
