I think stability should be prioritised.
From what I've seen of this league (only really this season), what strikes me is a significant lack of quality.
I'm not saying it will be easy next year, but I think if we stick with Bruce, build some continuity, add a couple of players, get a decent game plan, we will be just fine.
It's an added risk to put someone new in, let them choose the (possibly new) players they want, devise a new system etc.
Bruce in for me - would be quite interesting to get a poll too btw?
