The biggest problem with Clarke as I see it is that he has no mongrel about him. Opposition players are not hurrying to dispose of the ball around him, they are not just a bit nervous of standing in the hole in front of him when the ball is bombed in long, and they are not wary of taking him on in a tackle situation. He needs to start physically hurting opponents, intentionally, the way Sandi does. He is not as big as Sandi, but that shouldn't stop him dishing out a bump or two to keep opponents looking out for him, and worrying about what will happen if they get too fancy in Freo's forward line.
