"In 10 of the 18 trades, the difference in value among the picks traded was nine points or less, according to the chart," writes Michael David Smith.
Obviously this isnt the only tool GM's are using or it would be 18 out of 18 trades. This is evidence of tiers of value that deviate from the TVC. There was as much as a 120 pt difference in one trade, but the bigger the agreed tier is, the bigger the point difference.
An example of the DTVC in negotiations would be something like last year when I traded up for Julio Jones from 1.5 to 1.4. The person I was trading with (@SaleemtheDream) didnt think there was a large dropoff from Julio to Ryan Williams so he took the points the chart prescribed (200). If he valued a dropoff at 100 more points, I may still have done the trade but we will never know. He could've argued for another 200 more points to get value as if Julio was worth 1.3, or another 300 on top of that to get to 1.2. However, if he really valued him that highly, he'd probably just take the pick because he may not get that level of value in return, regardless if a chart said so or not.
At the least, the DTVC just as the TVC, can be used to set the baseline for many trades that may not get done otherwise and in many cases it can simplify and expedite the negotiating process.
