IMO - Griffin shouldn't be singled out for what was an absolutely pitiful performance by the team...
He was poor on the weekend and lacked a physical presence - but he wasn't alone.. there were a lot of other guys who didn't have a good game and IMO didn't put their bodies in when it was their turn..
Griffin was also made to look poor due to the game style we played on the weekend (and the week before against Melbourne was even worse).. All I keep hearing from Craig is we need to improve our ability to move the ball quickly and excluding the Geelong and Collingwood game, all I have seen is a major backward step on last year..
We chip and play around with it and then get to 70m from goal and bomb it to the top of the square, no wonder Porpy and Walker can't get a kick

If Port did that on the weekend, Griffin would have had 10 - 15 marks also and we would be saying what a good game and job Griffin did...
I have no doubt Maric is a better option in terms of contesting around the ground and his ability to go forward...
BUT he wouldn't have made that big a difference on the weekend.. Bogan is a very good ruckman and the Crows kept kicking it to him @ the top of the square.. ALSO The centre clearances problem is a coaching fault.. Given we couldn't win our own ball, we had to have a sweeper in there to make sure they had to break wide or backwards and that didn't happen...
In terms of personnel - I personally would like to see Stevens left up forward with Walker and Porpy and Tippett..
Play Moran / Bock / Rutten as the key backmen and have Maric and Griffin doing the ruckwork...
But that big forward line will only work if we move the ball quicker...
