I keep going on about the mental factor and how I think it's historically been lacking at the Nix
Yes, we peaked in mental "fitness" when we had Siggie, Manny and Tim Brown.
In addition, I would say it is hard to instill mental loughness if the team is being structured around young players being ripened up for a quick sale season in, season out. And if a young player is also mentally tough already, you would probably want to keep them, not onsell them.
