This is actually an extremely well-argued and pertinent post.
The problem with Grimes is that his technical aptitude and pedigree mask a worrying lack of genuine contribution. How many assists has he actually made this season? How many goals has he scored? How many significant tackles?
Crooks has some of the same problems, but a) I would argue that he's made more decisive contributions over the season (e.g. recently at AFW) and b) he's our player and is presumably more personally invested in the idea of us staying up.
For me, it's quite simple: we're scoring a decent amount of goals at the moment, but we're also conceding too many. The return of Facey will bolster the defence but using a more defensively minded midfielder in place of Grimes is the one move that would really make the difference.
Do you actually watch the games of just spout rubbish?
Grimes has assisted in the last three goals we have scored
