I think the most significant aspect of the Rovers sans-Baird is that we've now got our "number 9", Brian Graham, playing furthest forward as an out-and-out striker.
John Baird, who I remain a massive fan of, covers a lot of ground during a game, and while it has its many benefits, it often means that when the ball breaks inside the box, Baird is in the midfield or down in one of the corners.
He's like a one man equivalent of that Spanish formation at the Euros, when they played with a load of attacking midfielders and no "striker".
