Victor Martinez. This guy is going to become a solid top 5 finisher in every show he enters for many years to come. Also has great potential for becoming Mr. O in the future too.
Once Johnnie Jackson gets his conditioning down (and takes care of that gyno he always seems to have), he'll start having some great success, but I think that could still take another year.
My picks are Vic Martinez easily and I also expect big things from Jocelyn Pelletier.
