The Dallas Cowboys hired Bill Callahan away from the New York Jets this offseason to coach the offensive line and add offensive expertise across the board. Since his departure from New York, the Jets have surrendered 12 sacks in two preseason games and their offense appears to be in complete disarray.

Meanwhile, in Dallas, Callahan has overcome a ridiculous epidemic of injuries to his line, resulting in having zero experienced centers available for the first two games. During this stretch Dallas has only given up five sacks. Three in game one and only two in the Chargers' game.

Any self-respecting analyst would have predicted that Dallas would lead the NFL in sacks allowed at this point, given that they had no center and a mixed bag of non-starters at guard in the first game and only one starting guard in the second game. Instead, Dallas is better than or equal to, 14 other teams in sacks allowed.

Most importantly, protection for Romo was excellent for most of his passes in game two.

The credit for this improvement lies directly with Callahan. Callahan set offensive records during his stints with the Raiders and the Nebraska Cornhuskers and rushing records during his time with the Jets. He is widely known as a master technician and a tireless instructor.

Just as he did in his previous jobs, Callahan has worked with his Dallas linemen well beyond the scheduled practices to maximize their improvement in the shortest time possible.

But beyond his value as offensive line coach, Callahan may also add a West Coast flavor to Garrett's game plans.

After a very rough offensive outing in game one, in which zero passes were completed to backs, Dallas threw seven passes to running backs in game two. In addition, tight end James Hanna lined up as an H-back and caught a pass after swinging out into the flat, bringing the total to eight players catching passes out of the backfield.

Also noticeable in game two were several shallow routes to other receivers. This was no doubt part of the plan to protect Romo, but it's also classic West Coast football.

While it's true that it's hard to move the ball down the field with nothing but dinks and dunks, it's also hard to move the ball when your QB is constantly under pressure. West Coast systems like Green Bay's and New Orleans' have a way of balancing quick throws that help move the chains with deeper strikes that break open games.

Which is why those offenses have been league leaders the last few years.

Callahan's influence has the potential to bring the Dallas offense up to their level, provided they have guessed correctly on their guards and their projections for Phil Costa's progression as an NFL center.

The jury is still out on that part, but the Callahan hire is already paying dividends.
