I agree with what you say from a tactical perspective. However, against Rangers, we have tried that approach over the last, what, 20 years(?) and not won a single league game.
It's the exception, I know, but if we had just gone toe to toe with them over the same period, I suspect we would have won maybe a couple.
There needs to be a middle ground, and I'm grateful Robinson's press conference talked about simply trying to win the game rather than the endless years of "We need to be at our best and hope they are not" patter from a series of managers.
It is going to be interesting with two teams lining up with many new players. Regardless of the result, I don't think either of us will know where we really stand for a couple of months yet.
