It's certainly not ideal to come in at such a high level. The fact that Corbyn has been a backbencher for decades not only works against him in terms of lack of experience, it provides plenty of precedent for those who wish to rebel against him, given that he's been a habitual rebel. But there's nothing to be done about that: it's inevitable, in fact, given the leadership the party had for most of Corbyn's time in office.
