This is what I'd do, put Boyd in the middle for a lot of the game. We have enough cover down back with Suckling, Biggs, Wood and JJ (maybe even an Adock or Webb as well). That are Stringer spends much more time there, either way I think we need more contested grunt in the middle this week.
All little blokes up against Brown, Petrie and probably Daw...we saw how easy it was for Geelong's big dudes
