According to Dave Meltzer, wwe plans to let people go that don't show improvement within 90 days. This is mostly a wakeup call for recently signees (in nxt) who aren't progressing as much as they hope, not so much wwe vets.
Wwe just released 10 superstars on Nxt. Will there be more to come on Raw and Smackdown? Looking at the trends, i could see these getting the ax "soon":
Finn Balor- *shock pick
Mustafa Ali- *asked to be released
