you cant trade for depth players. lmao.
Imagine going to a player at another club and asking them to come to richmond, but we only want you as depth and will play you at coburg unless we have an injury or drop in form?
Gee, they would be falling over themselves to change clubs with that on offer.
Depth is only built over time through continued development, and if you get to a point where good players cant get a game, you will lose them to other clubs who have a need and can offer the game time they crave.
