While players are gung-ho about bringing Orr back, Baltimore's brass might not be so enthusiastic about signing a player with a congenital neck and spine condition.
One issue for the Ravens will be team doctors clearing Orr to see the field again. While the 25-year-old might have found a doctor outside the NFL to suggest he can play, it's not a given Orr will pass a team physical -- especially from the club that nudged him toward retirement in the first place.
Another issue could be compensation. The Ravens were in talks about a new contract for the breakout linebacker before his abrupt retirement in January. Clearly, the parameters of that deal would change. Interest from other teams will change the dynamics of what Orr can get on the open market.
Sheets said Orr has garnered curiosity from more than a dozen teams.
"We've spoken to 15 teams," Sheets said. "In essence, half the NFL is curious to do their own 'due diligence.'"
Lastly for the Ravens, the question is whether the team is content to continue forward with their post-Orr plans. Coaches have reportedly been impressed with second-year linebacker Kamalei Correa. The 2016 second-round pick saw limited snaps last year, but the team might believe he can manufacture a similar leap to the one Orr made in his breakout season.
