Re: Pre-Draft Trade Offer

You can use Average Auction Values as your draft value chart. The first pick costs $51 in an auction, the 73rd pick costs $10, plus you're giving up your last two (not four) picks worth $1 each, so you're giving up $63 worth of value. But his 3rd-6th rounders are worth $25 + $18 + $16 + $13 = $72, so you're getting back more value than you're giving up, which suggests that you should go for it.

If you have KUBIAK, you could also use its auction values to calculate the same thing. Sort the players by auction price for your league format, find the prices of the 1st, 27th, 46th, 51st, 63rd, and 73rd players, and see if the four you're getting add up to more than the two you're giving up plus $2 (for your last two picks).

If you make the trade, I'd recommend trying to get a top QB and TE, like Manning at #24 and Gates/Clark at #46 if they're available, since you don't want to just end up with strong RBs and WRs on your bench.

Dan's suggestion of auction values is brilliant: it puts a relative value on each pick

In a related manner, I'd suggest using KUBIAK to find what the 1st and 73rd player (and whatever your last two picks) are worth in Fantasy Points Over Baseline and compare them to the 27th, 46th, 51st, and 63rd picks. Whichever ends up higher is the one you should go with. Of course, there's the possibility you don't have KUBIAK, and there's the caveat that draft picks won't go in order that KUBIAK ranks them.

I think Dan's suggestion is probably best. It reflects what a market thinks about the value of individual picks - not players, as KUBIAK does. The players are as of yet unknown; it is the picks themselves you are trying to assess the value of, and that's what the auction values provide you.
