Next 7 games (and named 6N squad players possibly absent)
Bath v Quins (Bath missing 3E+3S)
Quins v Sale (Sale 3E+1S)
Sarries v Quins (Sarries 4+1S+1W)
Quins v Wasps (Wasps 1E+1W)
Worcs v Quins (1S)
Quins v Newcastle (1E+1I)
Bristol v Quins (2E+1W)
Got to target all home games and away at Bath (winnable), Sarries (they'll be missing 6, so a chance) and Worcs (winnable). Bristol away with them not losing too many players and revenge on their mind - that will be a tough one.
Do that, and I suspect top 4 would be secured...
IF that's possible, then last 6 games, with firm grounds and hopefully sunny weather, fight for home SF place.
