Update to my initial analysis:
Obviously a huge win for NCFC, and Sunderland drawing at home to WBA when I'd predicted a win is a bonus too. Palace pick up an unexpected point away at the Hammers.
Winnable = Bold, Draw = Italics "6-pointers" = Underlined
Norwich fixtures: Palace (A), Sunderland (H), Arsenal (A), Man Utd (H), Watford (H), Everton (A).
Palace: Norwich (H), Everton (H), Arsenal (A), Man Utd (A), Newcastle (A), Stoke (H), Southampton (A)
Newcs: Southampton (A), Swansea (H), Man City (H), Liverpool (A), Palace (H), Villa (A), Spurs (H)
Sunderland: Leicester (H), Norwich (A), Arsenal (H), Stoke (A), Chelsea (H), Everton (H), Watford (A)
So ignoring the fixtures where the 4 teams play each other, that gives a table:
Palace +3 = 37 (36 played)
Norwich +5 = 36 (36 played)
---------------------------
Newcastle +7 = 32 (37 played)
Sunderland +2 = 29 (37 played)
That looks an awful lot healthier. Of the remaining "6-pointers" remaining for the North-East clubs, wins for Sunderland (vs NCFC) and Newcastle (vs Palace) don't change the overall predictions, putting them to 35 and 32 points. From an NCFC perspective, that makes 5 points from our remaining fixtures sufficient.
Newcastle remain the biggest threat based on their comparatively easier run-in, but if they don't pick up at least a win in the next two games then they may leave themselves with too much to do. How quickly Benitez can turn them around is key.
Another nice tidbit, Villa can only now reach 34 points from their remaining 6 games, if we get a better result against Palace than Villa get at home to Bournemouth then we get to officially relegate them.
