Baltimore Ravens head coach John Harbaugh has revealed that he and his staff are eyeing potential free agents to add to their roster for their upcoming summer training camps.

The Ravens can add experienced players to their roster knowing that any signing they make could not potentially strengthen one of their rivals, as teams are no longer awarded compensatory Draft picks for any free agent signed after June 1.

"I think we're aware of the guys that are still out there, free agents that would be more favorable to sign after June 1 and all that," Harbaugh told reporters. "We're going to be watching the waiver wire real close.

"We're going to try and get better. We had a conversation, Ozzie and I [Thursday], and I like to think on principle that we really believe this.

"We want to build as strong of a 53-man roster as we possibly can, and as we do that [to] try to get stronger every chance we get. We'll be looking."

The Ravens missed the playoffs in the 2013 season after winning their second Super Bowl in 2012.
