The San Francisco 49ers have invested significant assets in the defensive line the past two years, drafting former Oregon teammates Arik Armstead and DeForest Buckner in the first round of the 2015 and 2016 NFL Drafts, respectively. The team has played in a base 3-4 defense during that time, but is now set to switch to a 4-3 similar to what the Seattle Seahawks and Atlanta Falcons run, which has raised questions about plans along the defensive line.

On Tuesday, new general manager John Lynch made an appearance on 95.7 The Game (audio), and he got a question about the team’s defensive changes and what it means for Armstead and Buckner. Lynch talked about the fact that the defense will spend most of the time in sub-packages, but he does think Armstead and Buckner are scheme-versatile. Specifically, he said he is excited to see them in a more aggressive role, rather than what he saw as read-and-react last year.

Here is the full transcript of his comments on the two linemen and the team’s new defense.
