Last 2 games against Geelong Hawkins has kicked 8 goals, Cameron 6 (from 1 game). Definitely a concern, we really have to prevent the number of opportunities up the ground. On the face of it Tarrant doesn't look like a good match for either of them. I'd go Miller acknowledging that he might get taught a lesson.
I actually think the opposite. Hawkins loves the wrestle and he's also a super smart player that you have to play from behind. If you let him get behind you, he will use his body (and sometimes the old approved shove) to get you out of the way and take the mark. We need experience on him IMO, and someone that can physically hold him. This is exactly why we recruited Tarrant, though obviously his injury may make this moot anyway, as he may not be physically able to play.
