Maybe I am simply reading the article different than you, but I am pretty sure that you just exemplified the exact new information’s in your post. I think the article was about how teams are more inclined to part with high draft picks now than they were in the past. I think it’s semantics if the selling team are demanding a higher price for their players, and thus the buying teams are paying the high price, or if the buying team are offering a higher price than previous, and the selling team is more willing to let their players go because of it. The important thing is that it happens now which it didn’t in the past.
In the end of your post you even describe the new trend. You are correct in your assessment, but to me, a new trend is almost the definition of new information.
IMO its showing teams have less faith in the draft so they are willing to trade higher picks for players who are already proven.
