Pretty much. JW has always been one of the one of the best camps, but their biggest selling point in the beginning was that they didn't charge fighters to train there, and provided room and board.
Doing that allowed them to draw the attention of talented, popular fighters, which caused regular gym membership sales to increase.
A strong stable of talented, popular fighters and a good monthly income; a win-win for Jackson's.
Seasons one and two of TUF were huge for Jackson's MMA. Diego was a weird ass dude, he was really good, and he won the contract; albeit at middleweight vs lightweight Florian. He would've beat an any weight Florian.
Evans and Jardine drew more attention for Jackson's. Evans, a natural middleweight, pissed off Matt Hughes, and won the heavyweight contract against Imes, a guy tree times his size, and won a UFC title.
Jardine was a goofy, sloppy brawler that didn't know how to have a boring fight. Who wouldn't want to hang out with the dean?
Shout out to Leonard Garcia.
Condit and Cerrone were two of the most popular and talented fighters in WEC. Cerrone fighting often (go figure), being a lightweight title challenger, and Condit as their final welterweight champ. Condit then won the interim UFC title to challenge for GSP's title.
Cerrone went on to fight on damn near every UFC card to date.
It has always been bittersweet to me that they were both at Jackson's. We were all very much robbed of Condit vs Cerrone.
Jon Jones.
Holm drew more women to the gym, probably some guys too, and demolished the unbeatable Rousey to win a UFC title.
Enter JacksonWink, the business. Moving to a much larger facility, the famed gym started charging fighters to train, though the names mentioned above remained uncharged.
Over time, the majority of the nonpaying veterans were losing the attention of the coaches, as most of their time shifted to the paying fighters. More money, more problems. Larger facility, larger expenses.
Fighters that were loyal to Jackson and Wink for more than a decade, who brought an enormous amount of attention to the gym, were being brushed to the side in favor of the new guys. Largely because the new guys are paying for their attention, and paying the bills.
Over the last few years, many of the original Jackson fighters have parted ways with JacksonWink.
