Even a win now approach needs some kind of plan or reasoning behind it. The Rams made the playoffs last year and seem primed to make a run, so a play to win now makes sense. The Cowboys revert to grasping wildly for a solution. It is Roy Thomas Part II.
The Cowboys gave up a one for what could be as little as a nine game rental. For a guy who hasn't exactly been lighting the world on fire, and is currently in concussion protocol. I don't remember the exact stats, but over the last 20 games, Amari Cooper has had four one-hundred yard games, the other 16? 40 catches for roughly four hundred yards. He has 22 catches right now. He Beasley and Elliot both have more.
I could see giving up a one for Beckham, or taking a flyer on someone like DeVante Parker with a four. Cooper? I could see giving up a three for him with his current production. Honestly? I think the Cowboys got played. Somebody whispered someone else was getting in, and they jumped and made a dumb move.
The Cowboys obviously disagree with your assessment of Coop's value. The move may work out perfectly for the Cowboys, or it may not.
My point was, an continues to be, that there is more than one way to build a contender. But no matter which way one chooses to do it, be it relying primarily on the draft, free agency, trades or some combination, all other things being equal, it almost always comes down to acquiring the right players more so than the method of building.
Take Gruden for example. He is using the Raiders' core players to acquire draft picks. He is using the "throw away "now" for the future", method. Most people think Gruden is crazy, yet this is the method that most media and so called "experts" seem to think is the best method, more or less, for building a contender.
If this plan does not work and in 3-4 years, the Raiders still look like a joke, Gruden will have cemented the current dim view of his abilities as a GM. On the other hand, if the Raiders are legit contenders in 3-4 years, he'll be hailed as a "football genius". At this point, it could go either way.
It's not the method, it's the execution.
