Does anyone know of a sim dynasty league that uses real rosters and minor league systems. I'm looking for something that requires 25-man rosters, 40-man rosters, or really just anything that will resemble an actual franchise operation, That also carries all 30 teams. I really just want the most realistic sim dynasty experience possible. Everything I've found has either used generated players or its system has made certain aspects of the game obsolete(i.e. middle relief, bench players, pitching rotations etc...)

Thank you in advance for any and all responses that may help me in my search.
