it's more of 4-2-3-1 which Grimes and Sheaf deeper - it's a similar shape to the Robins era team but Rudi has more of a freer role rather than the get as close to the stroker role he had before.
Grimes is great as he knits things together, offers great cover, is great on the ball and he has help cut out the stupid passed the cbs make as the cbs don't need to pass through the lines as the can just give it to him and he gets things going.
