What this also tells me is the club really didn't rate Gach in terms of pure footballing
Well whatever is telling you this is misinforming you.
So is it that we couldn't realistically develop Gach in our VFL side if we have 2 rucks on top of Gach in our VFL side (this year there were Jamar, Smack and Michael in front of him as ruck options), or was he not disciplined enough in terms of following club rules?
I think it is a no brainer to replace Smack if it is a choice between foregoing pick 41 or keeping him. There is going to be at least a 20 plus year old who will be a better ruckman available who is ready to go like Darcy Cameron or Rowan Marshall (even at a rookie pick), who still has upside to their development.
I'm not surprised that Smack prioritised getting his body right at the end of the season, because of his trouble this year being fit and the fact that we want a relatively physically reliable player as a back up ruck, given if they are not semi reliably fit, there is no point having them on the list if they are last in line for a game. But if we can get a better ruckman, we should be looking for one who can replace Leuey and TBC eventually, which isn't Smack either and unfortunately it wasn't Gach as it turns out.
