I don't see any reason why not.
I’m not convinced Erasmus couldn’t come in next week and do a decent job as an inside mid at AFL level tbh. What’s needed for him is that opportunity, which isn’t coming when Fyfe, Young, Serong and Brayshaw are available. Moving Johnson or JOM in there and playing an extra outside mid or forward (Switta more midfield) seems a better balance too btw.
