What? You mean you aren't the all knowing, all seeing Cowboys fan? Dude you're outclassed on this site, there's tons of "experts" here, don't you know? Better get with the program!
There is no simple, easy, one-sizes-fits-all answer, of course, though some here claim to have it..
It's true the Cowboys haven't, and probably won't, be a big player in free agency. But just bringing in a ton of high priced veteran talent is no guarantee of a SB win, or two, or even lots of playoff success. JJ, et al, have apparently decided to "dance with who brung ya", and who knows? It just might work...
