Bloodyelbow had the MMA Scouting Report by Leland and Smoogy which was excellent but they stopped doing it.
D.C. Ross of www.rankingmma.com is doing his own prospect report and its very good work.
He has the Flyweight list done. If you are a fan of checking out up and coming fighters I suggest you give this a look.
