I get the feeling, from Mueller's memo, that Flynn may have been offering WAY too much truth.
Flynn appears to have been talking to "other DOJ" investigators about "other" crimes he was aware of. Not sure that was part ot the "F Flynn then F Trump" op.
Maybe this sentencing recommendation mandates his silence (haven't read the details), which is the primary goal of Mueller's team.
Also, keep in mind, that this is only a RECOMMENDATION from the prosecution. The judge still gets to weigh in.
I would love to see Trump rehire him back into the admin.
