Everybody pretty much knows now that Brian Waters was once a great NFL guard. Some are now coming around to the idea that he might still be. And an overwhelming percentage now believes that, whatever he is, he's better than Mackenzy Bernadeau. Me, I think he's going to be the best offensive lineman on the team, simply because there's no history of injury and guard is more a position of strength than sheer athleticism. Age isn't the issue as much as health, and Waters has a history of being a very sturdy, healthy football player. Brute strength is far more hereditary than gym-built, and Waters has it. That, however, only scratches the surface of what this signing can mean. The impact is five-fold, if not more. 1. Waters provides the third wheel of a much stronger interior line, and that means a consistent pocket for Tony Romo. 2. Diversity in the rushing game. Where did Dallas run last week? To the left side, over and over. The Giants knew that, so even when Murray cracked through for a nice game, it was limited with the overload. Can't do that once Waters is established full time. Right or left? The defense will now have to guess and risk more. 3. Waters will benefit Frederick and Leary hugely. Despite a solid game, we're kidding ourselves if we think Frederick doesn't need experience. Waters is right next to the rookie to help, and he can tutor and mentor Leary all season nicely. Arkin stands to gain, too. 4. Waters will make Free better. The turnstile of junk that played right guard a year ago put Free out there on an island and ripped his confidence to shreds. He was vulnerable to edge and inside pressure, as well as any stunt a team could throw at Dallas. A solid veteran player inside him will do wonders. Free had a good offseason and is playing better than a year ago. 5. This isn't a one-year solution. If this goes well, Jerry no doubt will step up and pay the freight again in 2014. Waters only wants to play here, and if he plays well, we can do this one-year deal thing for as long as it works. It's because Smith and Frederick were good draft picks, and Leary and Free are average if not better, that this signing is going to have a terrific impact. No, you can't just sign a guard and move the ball with ease. But when it's a final piece to an offensive line puzzle, perhaps you can. Every player on the offense is going to benefit from this. Watch.
