Trades are fun, player movement is exciting especially when it involves a superstar, but there's a reason it doesn't happen that often.
Teams aren't just giving up on great players without being at the absolute point of no return. The Baltimore Ravens aren't there with Lamar Jackson yet.

At the NFL scouting combine, Ravens general manager Eric DeCosta was asked about quarterback Lamar Jackson. Jackson's contract is up, though the Ravens will use the franchise tag on him if a long-term deal can't be worked out. The Ravens can use the tag at any point until March 7, though the team is hopeful to get a long-term deal done before that deadline.
