Kassius Ohno was quietly released from his WWE developmental contract last Friday. While some might consider his release a surprise, that really isn't the case.
I was told in July that Ohno was very frustrated with his spot in WWE about not getting called up. He was on the short list to get called up to the main roster several times but every time he was tested with his "attitude and commitment," he failed the test. Weight training has never been Ohno's strong suit but his frustration was believed to be part of the reason why he wasn't receptive to increasing his workouts.
I'm not sure what eventually led to Ohno's release but Triple H was at the WWE Performance Center a couple weeks ago. Hunter was never a supporter and it was Vince McMahon that wanted to call him up.
