One of my fave quotes. Been in the investment game for a while...25+ years...and use it often, only second to Buffet's: "give your children enough to do anything, but not so much that they do nothing"
And yes, of course, using hindsight just as you are now employing what if's about the future (injury, etc.), which is certainly part of risk assessment...here's where I am coming from:
As a lifelong fan (since the 70's), it's always been the bold, unusual and often unorthodox move the has been the bastion of Cowboys' championships...
1) drafting Roger when he wouldn't play for 6 years
2) taking flyers on converted and sometimes non-football playing "athletes" who had the harnessable skillset to become great players (e.g., Drew Pearson)
3) working out to get the #1 overall for Tony D
4) Of course, the Herschel (sp?) trade
5) Acquiring the "miscreant" Charles Haley, which transformed the D to championship caliber...
6) I could go on...but you get the point...
In other words, the slogging through the mud of a methodical build has NEVER produced a championship for this franchise, but Lombardies have ALWAYS been the result of some bold and (sometimes) surprising move that changed the trajectory of this team to go on a run...I believe something like this AD idea (who the heck thought we would have EVER traded Walker???) is exactly the type of move this franchise needs to get their heads out of their nether region...I am getting to friggin' old to wait much longer for "the build" to yield results while we watch careers waste away (Romo, Witten, Dez, and on and on). You feel me?
