0-5 No idea who to start. Advice wanted.

Has the title said, I am doomed. I am still looking for the first win, which somehow keeps getting away. I am the player with the most PA (4th in PF), meaning that everyone that plays me has BOOMs. Very annoying. I have no idea who to start, especially at RB and who my FLEX should be. Please help. I want to win at least once. Thank you!
