Best way to create a completely generated ficticious roster?

[Rodzilla91]

Hey guys, not the most experienced roster creator, I don't think I'm even experienced enough to consider myself someone that can make the simplest of rosters.. however I was wondering if anyone knew a good way to completely wipe out all of the real world players and construct a roster with fake/generated players, whether using 2k's CAP generating system, or just changing stuff within REDMC ? .. I would like to know as I want to make a fake roster with custom teams, any help would be appreciated, thanks
