Not really. The 72 points is a better achievement in a tougher league than the fourth. You can only control your games in relation to your points. Hence it is reasonable to say 72 and 5th is a better season than the season Moyes team finished fourth (61 points). Everton had a -1 goal differential that year. Essentially the rest of the league was crap if you get fourth with a goal diff of -1.
BTW - This is not an endorsement of RM. I think he has proven unable to address the defensive failings either through his tactics or failure to drill players on defense. Either cause is his fault. He appears to have lost the dressing room with some players - and his positivity while admirable at first comes off as a bit "emperor has no clothes". For those reasons I don't think he will survive. The very best Everton can finish this year is 9th with 2 semi's. Not a great year but not dreadful as some would have you believe. I think we will probably end up 10th looking at the fixtures with 50 points.
@davek is correct in that the new manager will be judged under different criteria given the investment rumored to be coming occurs. However Everton fans feeling that we should win every game and moan that the manager is dreadful if we don't is unrealistic. The new PL with all the money will make it far more competitive than in the past - you can lose to any team. This is no La Liga or League One.
