Episode 6 - Cubs 4th and 5th Starters for 2022

We know who is going to be in the starting rotation in spots 1, 2 & 3 but who is going to take the 4th and 5th spots.   Adbert Azolay ended 2021 in the bullpen after starting the first 2/3rds of the season.  Justin Steele was stretched out for August and September but how did he do?  Is he ready to take on the 5th starter spot?  Keegan Thompson started a couple of games at the end of 2021 but didn't make it past the 2nd inning.  
I dig into the data and see what options the Cubs have for 2022.    2 of the 3 pitchers stepping up in 2022 would put the team on the fast track back into relevancy.
