The obvious answer is that it's too early to say.

The squad was in such a negative, self-defeating place when Mick took over that he didn't have to do much other than be not Neil Harris for things to improve and then when we were building momentum for real play-off run his bad game management cost us points against Watford and Stoke which was quickly followed by poor results against Wednesday and Forest - in fact the vast majority of performances and/or results after the 2nd of March were poor except for draw away at Brentford and win away at Brum.

We really don't know much about Flynn. I'd say he's done better in transfer market based on i) successfully signing players and ii) those players being playing well having arrived there but Mick's only had one full window yet.
