And I'll drop some logic on you regarding your own tendencies. You don't like it when things go badly for the Cowboys. And you go to great lengths to make excuses and soften the blow. As you are trying to do in this case. It's is a common position of yours, whether you choose to admit it or not.
As for there being 'worse football players than Crawford', that's a pretty weak 'argument'. There are also plenty of 'better football player than Crawford' available. As well as rons of young players who could have upside that Crawford clearly doesn't. 'Bad' doesn't due Crawford's performance justice. He's doing NOTHING well, and he is, in fact, a total liability out there. Run over, run around, run through. He's not even recording stats at this point. There are guys on the street or on other teams practice squads that can do better. You know it and I know it.
If you need a list of better candidates, I suggest checking out Spotrac or other sites that list available free agents. There are plenty. And as I've said repeatedly, a blank roster space can get me ZERO STATS, and at least they won't give me a 15-yard taunting penalty. This clown is actually a negative.
