Jun. 27, 2013 @ESPN_NFCEast: No, but I dispute the notion that improvements at those positions were the most important thing for the Dallas Cowboys to do in order to make the playoffs. I would argue that improved health on defense is the key to their season. If they had engaged in a more extensive offensive-line overhaul, I might have said yes to your question. But all they really did was add first-round draft pick Travis Frederick at center. I like that move, and it will help, but it doesn't exactly solve all of the problems. Nor does replacing Gerald Sensabaugh with Will Allen and hoping Matt Johnson makes an impact at safety. They couldn't do much this offseason and didn't, which means the key for them getting out of the 8-8 rut is for the players who helped get them to the brink of a division title each of the past two years to play a little bit better and stay a lot healthier than they did in 2012. Think about it this way: If Sean Lee, Bruce Carter, Jay Ratliff, Barry Church and Orlando Scandrick all stay healthy for 16 games, isn't that going to be the rough equivalent of a massive free-agent haul on defense? Graziano thinks it's the defense and I think this is a big part of the equation but I think RZ performance for the offense is another key although that's on both the D and the O. The other part of the golden key to success is turnovers esp differential. Gotta get outta the red there. Anyway, it's the offseason and I thought I'd throw this out there to be rehashed....again. Here's my contribution. I'm worried about safety like most are but I don't like the CB situation either. I'm worried about Carr and wasn't really that pleased with him last year. He looks slow and not so quick either. OScan has always been inconsistent AFAIC. Claiborne is a sophmore. What's his year going be like? I love the Webb pick but he's a rookie although I expect him to contribute. And I like Moore but can he start? Where's the depth behind those guys? Can they tackle well enough to play this defense?
