I don't agree that the overall direction is upward. I think we are a poorer team than last year with poorer results. At best I think we are standing still, but I actually think we have slipped slightly backwards.
That said, BR is one half-season into the 2 season timescale that I think you should give managers so I'm not suggesting getting rid.
Let's hope that 2013 shows some steps forward that no-one (even me!) can disagree over!
