I guess there will be two schools of thought.
One, that a wounded animal is a dangerous animal, and that last weekend will have been a wakeup call to the Bath squad. They are individually good players, for the most part, with some being exceptional (e.g. Sam Underhill), so they will presumably click at some point and, the shame of Sarries may well spur them on to exceptional things this week.
The other school of thought will be that they are so disorganised and demoralised that if they concede a couple of scores early, heads will go down, memories will come flooding back, and it could be a bloodbath for them once again.
I'm sure that Tabai and the coaches will have prepped the Quins team very well based the first of those scenarios, but should we worry that we may still come into the game overconfident after the successes of our first three matches and Bath's appalling record so far this season?
My personal worry would be that Sale outmuscled us last week up front, and, that when a team can manage that for the whole 80 minutes we look distinctly vulnerable. Can Bath do that?
