We will never really know if Keane has been a good appointment, just like we don't really know who did what on the coaching/tactics front when Culverhouse was here.
Of course there will be meaningless platitudes from within the club about what a great contribution he is making, and some will be eager to credit any improvement in the team or an individual player's form to Keane even if there is no basis for that.
I'm not a fan of his myself, but let's hope he brings some positives.
