As to change in the offensive line...no, not another Jerry slamism:
...When the
Dallas Cowboys lost former offensive line coach
Frank Pollack this offseason to the Cincinnati Bengals, the Cowboys brought in
Paul Alexander to replace him. After spending the past 23 seasons with the Bengals as their O-Line coach, the legendary Alexander was never quite able to get the most out of his lineman in Cincinnati. Now, with the Cowboys, he looks to be having similar results.
The play of the offensive line has suffered without center
Travis Frederick but that doesn’t account for the poor technique shown from tackles
Tyron Smith and
La’el Collins. Neither player has looked the same this season. Both appear to be giving up more pressures then they have in the past.

According to
Pro Football Focus, Collins has allowed
a team-leading 20 pressures, 16 hurries, and seven penalties (two declined) so far this season. While Smith has racked up 12 pressures, 10 hurries, and four penalties through seven games.
Alexander hasn’t seemed to be able to fix whatever has been wrong with Smith or Collins’ techniques. And if he is unable fix the problems over the bye, it may be time to find someone new. Dallas does have
Marc Colombo as their assistant offensive line coach...
