This pretty much mirrors my views.
As a supporter, whilst being purely speculative, I believe ANB will stick around. From all reports (interweb postings) he appears to know his place in the MFC pecking order but wants to earn his spot. I'd also easily have him ahead of Michie, Newton and Terlich and should remain as a depth player (at worst).
Trengove I'd probably rookie, similar to what we did with Jetta. It gives us a way to promote him, without having to cost us a spot on the senior list. Sure, he's coming from a long way back, but I have a belief he may be able to return. But who knows, maybe this is just MFC rose coloured glasses. Only time will tell.
Terlich, Newton and Michie surely have played their last games. Grimes? I'm not too sure about him, I suspect he'll be on an AFL list next year, it just remains to be seen where. I wouldn't be entirely upset if he was to remain, but depending what sort of player we could replace him with, if he were to leave it may be for the best.
Garland and Dunn are interesting too. IIRC Dunn has a year to run on his contract, given that, I suspect he may stay around. He's of fairly little currency. But that places Garland in an interesting position too. I can't see both of them being on our list next year.
