Yes, and in the games before he took over the only team we hadn't played from the top 6 was Liverpool, so the fixture list is completely irrelevant.Since Sam took over I think we have played thirteen games, as you say we were eight points clear then , we are the same today after playing Liverpool, Chelsea,Man Utd, Spurs and Arsenal in that time. The only team from the top six we didn't play was City.
I think your summary is correct, not terrible, not particularly good... best described as "safe" which is why I think he got the job.
I agree that he was brought in as a safe pair of hands, and he's done what was expected, no more, no less. I'm not someone who'll sit here saying he's the worst manager ever, it just really winds me up when people go on about how he's saved us or he deserves another season just because he hasn't monumentally buggered the whole thing up.
If we're even remotely serious about becoming a force again, we need to get rid at the end of the end of the season and bring someone in to start moving us forward. I can deal with that taking a few years as long as I can see tangible signs of progress, but sticking with Allardyce would simply be a year wasted in my view, and may even have a detrimental effect on our long term prospects.
