Starting Monday, the Titans will have a two-week window to use a franchise tag on one of their free agents. The team isn’t expected to make the move immediately, however. While the Titans aren’t obligated to use the tag, they’re expected to do so — on tight end Jared Cook. The Titans don’t want to lose Cook, and reaching a long-term deal with him soon isn’t expected. The franchise tag for tight ends is expected to be roughly $5.967 million. Cook, who has 1,717 receiving yards and eight touchdown catches over the past four seasons, is currently rehabbing from shoulder surgery. He’s expected to be ready for minicamps in June, however. Titans kicker Rob Bironas would be the other option for the tag, which would cost the team only about $2.928 million. Signing Bironas to a long-term deal right now figures to be more realistic than getting something done with Cook, however. The deadline for the franchise tag is March 4. A year ago the Titans placed the franchise tag on Michael Griffin, but later removed the tag after reaching a long-term deal with the safety. Center of attention?: The Titans have 18 players scheduled to become unrestricted free agents on March 12, along with one restricted free agent — center Fernando Velasco.
