The Titans prepared for this weekend's rookie camp by signing the last four of this year's seven draft picks to contracts. ... Ahead of that camp, veterans are engaged in organized team activities. One person who is not there -- but is coming -- is veteran wide receiver Tyler Boyd, who previously played in Cincinnati and had new Tennessee coach Brian Callahan as his offensive coordinator. ... Along with DeAndre Hopkins and Calvin Ridley, Boyd gives the Titans three veteran wide receivers who have combined for more than 1,700 receptions in their careers, which is a far cry from the inexperienced, unproductive group they had in 2023. Boyd's familiarity with Callahan's offense should help those others, plus quarterback Will Levis, get up to speed more quickly. ... Boyd's addition is not good news for 2022 first-round draft pick Treylon Burks. By all accounts, Burks is having a good offseason. But every indication is that he is no better than No. 4 on the positional depth chart. Callahan continues to say that Burks will get what he earns in terms of playing time and opportunities for receptions. It is likely that he will have to work extremely hard to get any opportunity. ... Levis noted that there are two notable differences with Callahan in charge rather than Mike Vrabel. First, the second-year quarterback has been told that the Titans will throw the ball on early downs and in a variety of situations. Second, there is more give-and-take between players and coaches, which has made a number of previously quiet players feel comfortable about speaking up and adding energy. ... The rookie camp will be the first opportunity for some first-year players to show they are up to the task of being professionals and possibly could make significant contributions in 2024.
