The Dallas Cowboys haven't had the season they envisioned having and they are likely going to be sellers at the trade deadline, with their first trade taking place on Tuesday.

According to the NFL Network's Ian Rapoport, the Cowboys have traded Everson Griffen to the Detroit Lions for a late-round pick.

Shortly after Rapoport reported the trade involving Griffen, he shared that Dallas is getting a conditional sixth-round pick in return.

It was discovered earlier this week that Griffen could be shopped around by the Cowboys ahead of the NFL's trade deadline. Given that, it's not a surprise to see Dallas pull the trigger and move the veteran defensive end.

Griffen signed with the Cowboys before the season and was expected to be a key contributor on the defensive front. However, he's tallied only 2.5 sacks and doesn't appear to be as explosive off of the edge as he once was with the Minnesota Vikings.

Maybe the Lions, who have won two games in a row, can help Griffen revert to being a formidable edge rusher. Matt Patricia's defense has accumulated only eight sacks as a defensive unit so far this season. That is the third-fewest sacks a defense has produced in the first seven weeks of the season.

Therefore, even though he's a shell of his former self, Griffen could possibly ignite a light in Detroit's pass-rushing department. On the other hand, it appears that the Cowboys are officially undergoing a fire sale and are unloading veteran players for draft capital.
