Generally speaking - I agree with this take. Giving up high end draft picks and cap space is not a good strategy - unless it is so solely put you over the top or get a qb. And even the solely to put you on the top is something I struggle with.
As much as Cowboys got ripped - while I think they should have found a team where the first round picks would be better - I didn’t mind the trade. If I were them I would move Dak for some picks too and actually jump start a rebuild.
In general, I think teams could benefit a bit more in NFL from trading guys at max value vs holding on too late and than leveraging cap space for those difference makers and than using it for more late round picks for good players with just a bit left (as they tend to be under valued in terms of draft capital).
It is like DJ Moore - if I could get 2 2nd rounders and cap space for him I probably do it - same with Jaylon. Having that allows you to continue to bring in young, ascending talent while giving you cap space to retain your own and buy guys that fill your void.
