Are you saying all the players were really old with one exception? If so, you have now certainly lost your mind completely.
I have mentioned a lot that I agree that the first Martinez season was fantastic (it is hard not too and I doubt many would disagree) and an improvement on the last couple of stale(ish) seasons under Moyes, however, let us then consider the next 2 seasons shall we. Where we finished in the bottom half twice, so that is 2 years out of 3 finishing 11th, Moyes finished in the bottom half 3 out of 11 years. Now if anybody took a dads army and rejuvenated an Everton set up I believe that was Moyes.
The easy argument is that Martinez was starting to mould his own team then and failed miserably.
