Buddy's still out, isn't he?
Forget about bringing in another tall, I'd be thinking pretty hard about dropping one.
Hale's down there a bit, and Schoenmakers' been down there for patches here & there, but outside Roughead their talls are nothing to worry about too much.
Recently, the Hawks' goals have come from Gunston, Lewis, Rioli, Breust, and Roughead (who we've always managed pretty well)
Gunston's the tricky match-up, he's not a bona-fide marking target, but IMHO he'll be too quick for Fletch, Carlisle or Hooker; and will probably out-do Hardingham if the ball hits the deck. Hibberd would be a good match-up.
Perhaps we drop Hooker or Carlisle, and run Pears on Gunston, Fletch on Hale/whoever. Would perhaps make some sense, but I doubt it - they'd back us in to play it on our terms, and make Gunston try and win the ball deeper; where Carlisle/Hooker would probably have it over him.
