I see that now my league is past the trade deadline, I can't see the trade value of any players and I can't propose any trades. I think this could be changed.

While trades absolutely shouldn't be concluded past the deadline, I should at the minimum still be able to see the trade value of players I might want to move or go for once the window reopens, and at least that would allow for trades to be made verbally if required.

Leave everything as is. Just disable the actual button that makes the trade offer go live.

I would like to see the trade value displayed on the player card (details page) at all times.
