Pace, who fired his agent, Carl Poston, during the season, is still in the process of finding a new agent. He had been talking to Tom Condon of IMG and Rocky Arceneaux, but he has not announced who will negotiate his contract.
By giving Pace the franchise tag, the Rams must increase the price of last year's designation by 120 percent to $8,425,100 in the form of a one-year tender. Both sides have until March 15 to reach a long-term deal and still allow the Rams the chance to regain the franchise tag for next season.
If no deal is reached by mid-March, then negotiations will cease until the summer. After July 15, the two sides can start talking about a long-term deal without the team losing the ability to franchise for the length of that deal.
Pace, 29, becomes the third player this week to be tagged. He joins Jets defensive end John Abraham and Eagles defensive tackle Corey Simon as players who have been tagged. About a dozen or more players are expected to receive the franchise or transition tags.
