I'm inclined to say Greg Jackson's camp is the best out there at the moment but it seems that the fighters don't spend as much time there as they do with the other camps. This is in terms of developing talent. The best team in terms of the best collection of fighters is Black House/Team Nogueira. They arguably have the top middleweight, light heavyweight, and heavyweight, along with a couple of really interesting prospects.
went with Couture. It was them or ATT. Both have great fights, but they have more than other camps. Nogeuria/Silva's camp has 4-5 great fighters and a few prospects. Couture's camp is just stacked with a boatload of talent and it seems more and more fighters are migrating to the camp as well.
