I would like as little as possible interference of trades. If a major league manager makes a bad deal there is no one there to say "oh sorry that's not in the best interest of your team or the league: you can't make that trade." Part of fantasy baseball is to recreate the feeling of being a major league owner/manager. Therefore, I feel that unless the trade is utterly ludicrous, such as Giambi for Orosco, LET IT RIDE. With the issue of prospects, it's simple. Prospects are just what the title says, prospects. They may be good, they may blow out their elbow ( or some other less mentionable part of their anatomy) but prospects are the basis of many trades. It's up to the managers to do their homework and take the chances on trading for such players. Same can be said of veterns recovering from injury. You want to take a chance on them, you are willing to pay the price, you live with what you get.

I understand that the evaluation is mainly to keep friends from trading valuable players to their buddies for a nickel,(and vice versa later) in order to gain an advantage: that is where true trade evaluation comes into play. If it is beyond reality of what would really happen in MLB ( say if you traded Millwood for a career back up catcher, oops that actually happened) it would have to be evaluated as "insider trading" and damaging to the competitive spirit of PB, and therefore rejected.

The safeguards are in place, the judge is reliable, LETS PLAY BALL.
