I have no problem trading up with a third to get their man even if they "lost" the trade by the standard charts.
The thing we have to keep in mind is that we had a surplus of draft picks the previous couple years including 6 in the first 3 rounds last year, all of whom will be on the team so eventually you have to start consolidating picks. There isn't unlimited roster spots.
We're at the point where the roster spots we have available need to be used on high end talent not your standard mid to late round draft pick so if you have to "overpay" to get that high end talent so be it.
