The importance of linebackers in the NFL has grown, as more teams are attacking the middle of the field. Super Bowl LVIII will feature two strong linebacking corps: the Kansas City Chiefs and the San Francisco 49ers. The 49ers have influenced other teams with their offensive scheme, which requires linebackers who can run and be versatile. The Philadelphia Eagles have struggled with their linebacking corps, prioritizing other positions in team-building. However, the Chiefs and 49ers have shown that investing in linebackers can lead to success.

The Eagles' linebacking corps has faced difficulties due to injuries and a lack of depth. In a game against the 49ers, the Eagles' defense struggled, giving up a significant number of yards after the catch. The 49ers' offense, led by coach Kyle Shanahan, consistently attacks the middle of the field to exploit matchup advantages. Shanahan's scheme puts pressure on opposing linebackers, emphasizing the need for athleticism and speed in the position.

The 49ers and Chiefs have prioritized linebackers in their team-building strategies. The 49ers' general manager, John Lynch, and coach Shanahan have focused on developing a strong linebacker group as the centerpiece of their defense. The Chiefs' defensive coordinator, Steve Spagnuolo, also places a premium on linebackers who can run and cover, given the increasing athleticism of tight ends in the league.

The Eagles' draft investment in linebackers has not yielded the same results as the 49ers and Chiefs. Despite spending less money on the position, the 49ers and Chiefs have built stout defensive lines and have quality starters in their secondaries. It is possible to develop a strong linebacking corps without using early-round picks, as demonstrated by the Chiefs and Flajole's previous experience with the Eagles.
