The Baltimore Ravens currently sit at 4-5 this season, but they are in no way out of playoff contention. It will take a lot of work to get the team to rally and start picking up some wins, but the addition of quarterback Jacoby Brissett could lead to just that.

Quarterback isn't the only position that needs an upgrade, though the others are out of need and not a deep necessity due to injury.

Here are three players the Ravens should target ahead of the trade deadline.

The Ravens already made a deal to bring in center Cam Jurgens, but now they should be looking to upgrade their offensive line. Not enough has been done, and the current line is one of the weakest aspects of this team.

If the Philadelphia Eagles are looking to trade Landon Dickerson, the Ravens should make a call to land the guard. Something drastic needs to be done to either push more competition, or to simply find an upgrade.

Brissett cannot go through what Lamar Jackson, Tyler Huntley, and Joe Fagnano went through if this team has any chance of rebounding.

Baltimore needs secondary help. Whether there is an issue with playcalling or the simple fact that Marlon Humphrey continues to trend downward, something needs to be done.

Again, the Eagles could be engaging in a fire sale, and the Ravens need to have the wherewithal to realize there is a big issue in their current coverage. Should Kyle Hamilton be out due to the hip injury he suffered in Week 9, a big swing at some secondary help would make a lot of sense for the defense.

Humphrey is running on an expired contract and the Ravens may need to find his replacement, which could be Woolen. 

Yes, you read that right. Yes, it is time to revisit the failed Maxx Crosby trade. 

The whole idea was to get Crosby and Trey Hendrickson playing together, and why not have general manager Eric DeCosta improve the ailing pass rush? The Las Vegas Raiders may not be open to hearing anything about their All-Pro edge, but a ridiculous offer may sway them yet again.

Crosby continues to dominate, but the fractured relationship between him and the Raiders organization may still be present. 

If there was ever a time for the Ravens to take a really big swing, it would be now. There might be a case for the team to trade Calais Campbell, leaving the door open to bring Crosby in.
