While you can freely exchange your team during a match with the 6 core players (like if you have all 6 online, you can freely exchange each other in a match), this isnt possible with the extra backups.
As you have noticed, I never told you that 2 of the 6 are backups. I told you that your team can be 6 players large. And that was on purpose.
