Let's be honest here no other NT have starters that play for lower divisions during their club season. It's ridiculous. Everyone is subjected to a high amount of pressure to perform well at a level where they should be growing further. It's nearly impossible to gauge someone's growth in a lower level. And you just know they'll get that automatic NT ticket regardless since they agreed to play for Manabe's domestic team.
I think Manabe has to be desperate to make sure things go well. He hasn't produced a lot of results like he promised. Come next year things will escalate. This year was his experimentation phase so he can still shuffle some players but by next year the team he goes with has to be rock solid Paris team through and through no time for any more changes.
