101ESPN St. Louis audio: Cardinals' OL

After some initial discussion regarding Russell Wilson, my weekly "Fast Lane" discussion on 101ESPN St. Louis turned to the Arizona Cardinals' offensive line.

Co-host Randy Karraker has been paying attention to what has been a shifting conversation this offseason.

The line was widely considered a disaster area immediately following the season even though the injury-ravaged unit had made significant strides.

First-year coach Bruce Arians expressed confidence in the group, even calling left tackle Levi Brown an "elite" player at the position. The Cardinals then used the seventh overall choice in the 2013 draft for guard Jonathan Cooper. They used a fourth-round choice for another guard, Earl Watford.

Now, there's a growing sense the Cardinals' line should be vastly improved. Karraker, co-host D'Marco Farr and I pick up the conversation from there. Here's the audio.

Chart key: The San Francisco 49ers had five offensive linemen start all 16 regular-season games. The Cardinals had two start 16 games, three start between 10 and 15 games and three start between one and nine games.
