interesting article on draft pick values

The data suggests that the NFL (or Jimmy Johnson) draft value chart drastically undervalues the picks from the latter half of the first until deep into the third round. Particularly it brings into specific relief the lunacy of the cost of moving from the mid first into the top 10.

In essence, on teams that are "one player away" should think about trading up in the early rounds.

My only criticism at this point is that it doesn't directly take into account the quality of the starts, nor does it seem to take into account rotational players who don't start.

So, what do you think about the data?
