The new player trade block is a Good Feature... up to a point. More useful would be a new player contract block (new players cannot sign new contracts for 30 days) since that's where many of them come unstuck, and then, unable to trade away players that might bust the team cannot be helped by other members of the league.

Two requests:
- Admin ability to void contract changes for a team, reverting them to the previous contract on a player (avoid busts)
- Admin ability to cancel trade limits for new players (avoid busts)

Adding my usual caveat here - yes, a corrupt admin could abuse this system, however I hold firm to the idea that corrupt admins will spend most of their time on the "leagues seeking owners" lonely hearts club.

Your idea is similar to mine. I would like to see a probationary period, similar to trades, where new players simply can’t sign, cut or trade for players that put them over their salary cap. Not only would this help train new players to be mindful of their spending, but there would be no concerns over league admins doing something untrustworthy.
