Before i put my point across here, let me state I am aware of how dismal some of the performances with Rhino in charge where. However, were they any worse than what we are currently witnessing? I think not.
What allardyce and his team have done is rubber stamp the disillusionment amongst the fan base which Koeman had begun. Whilst performances under Unsworth were generally poor, there was a bit more of the backs to the wall attitude which generated a little fight throughout the club (Watford home for example).
Now let's consider the games Allardyce has won whilst in charge.
Huddersfield (h)
Swansea (h)
Newcastle (a)
Leicester (h)
Palace (h)
I honestly believe that we would have won all those games had Unsworth remained in charge and ended up floating round mid table as we are now. Huddersfield and Swansea were woeful at the time and required only two crap ish performances from Ourselves to beat them. Newcastle we were lucky but still it was two poor teams. Leicester and Palace we were helped massively by circumstances and both Zaha and Mahrez missing. Granted, Allardyce has picked up odd points here and there through his park the bus approach, but again, maybe we would have beaten WBA on one occasion which would compensate for another draw/loss elsewhere.
Essentially, the board panicked after Southampton and were panicked into making rotten managerial and coaching appointments which is ultimately going to do nothing other than create a further divide between the fans and the club and then cost the club another small fortune to pay them all off if (likely when) they are removed. If the board had given Unsy the games against Huddersfield and Swansea, won the, both and them come out and stated he is the Mann for the rest of the season as anyone else we may want isn't currently available, I think most Evertonians would have accepted that as a stop gap.
As fans who go week in week out we should expect better and demand better from 'professionals' who are in charge of the club.
