The Carolina Panthers are in the league's bottom third in run defense, as they have surrendered an average of 127.4 yards per game.
Defensive tackles Ron Edwards and Dwan Edwards need help in the middle, as neither has been able to control the interior on the defensive line throughout the course of an entire game.
While poor tackling has also contributed to the defensive woes, another big body would, at the very least, keep the interior defensive linemen fresh.
If the Panthers decide to pursue a defensive tackle before the trade deadline, they will do so knowing that it won't be easy to acquire an adequate one.
As mentioned in the introduction, the trade deadline in the NFL is the least active of the major sports.
Organizations that build through the draft tend to be more successful long term, so front offices tend to be very conservative in trade situations.
At 1-4, GM Marty Hurney is in a precarious position because his team faces an uphill battle to qualify for the playoffs this season.
The Panthers could target Domata Peko of the Cincinnati Bengals or Alan Branch of the Seattle Seahawks, both of whom could be available at the right price.
Coming into the season, Carolina's run defense was viewed as an area that could be improved. Through five games, it is clear that the run defense still needs to be improved.
Hurney has to be proactive in improving the teams' run defense, but also can't afford to give up too much for a questionable run-stopper.
The Panthers need a defensive tackle, but Hurney shouldn't offer more than a fourth-round draft pick unless an amazing opportunity presents itself.
