I think probably 10-12.
I don’t totally blame Bischoff, as he’s intimated many times before that there was always the “problem of more” under the corporate leadership. They could really have cared less about the actual quality of the content versus just simply having content to put on their networks to try to drive ad revenue (basically the entire reason Thunder was created at Ted Turner’s demand). For a certain time, if you were writing or booking shows, towns, etc. it was probably all too easy to just throw in some NWO here and there whenever you needed to jumpstart interest or ratings, and besides, even in a faction, the thought process was probably that someone had to do the losing.
I still don’t think it had to get to the point where you needed 30+ guys, but to a certain extent I can understand why it did.
