I see this as Blackett saying that he can sort the backs out with minimal recruitment, providing the forward pack is dominant.
We see at other clubs that a dominant pack can make some comparatively average back lines look very good.
We also know that Blackett's primary role in the past has been a skills/backs/attack coach.
On paper, we should have a very very strong forward pack next season.
Not just a strong scrummaging unit, but one that should be strong in open play and at the breakdown too.
If that does translate to our half backs getting a fraction more time at each play, then we have no excuses if our backs struggle to create much next season.
I look forward to seeing the results
