Anyone have an idea how the yahoo "evaluate" button works on trades. How is the algorithm like? What does it do to come up with the trade numbers. Does it just average out all the players at the positions? What are people's thought on this "new function"?

I wouldn't put to much seriousness on any computer generated trade analysis.

BBM's trade analysis is useful. Yahoo is a steaming pile. I don't understand why they don't just get a fantasy player to tell them what to build. It's not rocket science.

I dunno but I HATE the fing fact this tool exists. It serves as another rutch for gms who arent smart enough to do math and their own analysis on trades etc..

Don't like it and agree with the above. I've pulled out 2 trades so far this year doing my own analysis and I've done we'll since those trades. I'm not sure what r&d went not this tool but it should have stayed with development instead of being published for this year' fantasy basketball season.

My league moved from yahoo to espn and I think it's much better. I use bbm for trade analysis sometimes and it's good. I really like espn's player rater over yahoos straight numerical rankings. Espn's shows you how many standard deviation a player is above or below the league mean for each category. Much better than a simple number rank.

BBM is a good tool but it is just that a tool I know owner's some leagues who view it as the ultimate analysis. I know owner's who use it as a selling tool in a trade. In fact, I have occasionally. But, it is just a tool not the final determinant on whether a trade benefits one side or the other, or both.

I don't use the Yahoo! trade analyzer. What I found in football is that it uses projections that were made well in advance of an event (e.g., an injury). I recall that with Greg Jennings it was still predicting 12 to 14 points per week even though it was clear that he was going to be out for an extended period.

I can't see it being much different than BBMs, although I dont pay for BBM so really I can't say. Or ESPNs if they have one. It is all based on projections anyways so really you are putting your faith in someone else's knowledge of the game. In that regard I am inclined to trust BBM more than Y! (or ESPN) but that still means very little whan analyzing a trade.

I've played around with it several times, during different weeks... the numbers change. I even tried doing a trade that was obvious improvement for a team but showed otherwise. Very Strange.... was wondering what others thought.

I also agree, it's probably more destructive for people who like to do trades because it creates a 3rd GM (Yahoo) to say it's fair. The more decision makers, the harder to pull trades.

I haven't used it at all, but if you can work out which players have over zealous projections from Yahoo and which ones do not, then you can target those trades so it looks juicy from your opponents point of view.

Where are you seeing the standard deviation for the player rater?
