My question to you is what was the most stacked/most successful franchise you've ever been apart of? Given the CPU makes trades and signs players, it's hard to get a really nice roster.
Mine happened recently with the White Sox. I'm a Mid-Rotation SP, 20 years old A Potential, in 2018. We made it to the World Series last year, but didn't win:
BATTING:
1. RF Adam Eaton
2. CF Rafael Ortega
3. DH Jose Abrue
4. 1B Eric Hosmer
5. C Jonathan Lucroy
6. LF Melky Cabrera
7. 3B Todd Frazier
8. 2B Ceaser Hernandez
9. SS Tyler Saladino
PITCHING
1. LHP Chris Sale
2. RHP Chris Archer
3. LHP Carlos Rodon
4. LHP Jordan Brennan (RTTS)
5. RHP Mat Latos
RPs: Pedro Strop, Brian Matusz
SU: Hector Rendon, Tyler Clippard
Closer: David Robertson

I did notice however that the Cubs added Cespedes so now their lineup includes Rizzo, Bryant, Schwarber, Cespedes, Heyward. That's nasty.
