I wouldn't be surprised if Mitchell is one who misses a few games from here on. I'd say he's pretty safe in keeping his spot for next year, there's others who are more fringe selections on the list who might get given a go at AFL level to see if they can play:

"It is a great balancing act between trying to get exposure to a lot of young players, which we are doing, but there aren't too many players that we can take out to get games into someone else," he said.
"We would love to get Mackenzie and Hustwaite and Long and Serong, Ramsden, they are all players we would love to get into the side and see what they can do. How we manage it and how we get players in is a balancing act to get as much development into the squad over the course of the next six weeks."
Might not be the only Hawk who gets "managed" from here on. Could be wrong.
I'd pick the best player and not worry too much about loops, but you're also in a far better position than me.
