I don't think any of them are a loss including Eli Cottonwood, i never rated Salazar. I think they are just making room for the new talent they have been signing.Would be sorta scummy to have Salazar drop his mask and then release him. Maybe he asked for his release - he was basically squashed his whole tenure so far.
No big losses really - Jiro was forgettable and I don't believe Sonny Elliot ever even wrestled on television.
It's weird that they remove guys, change Bo Rotundo to Bo Dallas but can't change Harris to Bray Wyatt. I just figure they're waiting for the NXT relaunch for a new site altogether.
