The Arizona Cardinals are facing intense competition at several key positions as they kick off training camp. Among the most notable battles is the defensive line, where eight players are vying for just six or seven roster spots. Prominent players include Calais Campbell and Dalvin Tomlinson, both of whom are expected to start, given their extensive experience and success in the league. However, a calf injury to rookie Walter Nolen III and lingering issues for Bilal Nichols may impact the roster dynamics.

The situation is compounded by the fact that the Cardinals utilize a rotation system on the defensive line, making playing time more accessible for a wider range of players. The team’s history of rotating personnel suggests that even those who may not secure a starting spot will still receive significant snaps throughout the season. The upcoming weeks will be critical in determining who will solidify their place in the Cardinals' defensive strategy.
