BUFFALO Jakeem Grant Jersey , N.Y. (AP) — Buffalo Bills general manager Brandon Beane promised he’d be “judicious” in rebuilding his team in free agency.With more than $70 million of space available under the salary cap, he’s also proving to be busy.People with direct knowledge of discussions told The Associated Press on Monday that the Bills agreed to sign center Mitch Morse, tight end Tyler Kroft, running back Frank Gore and cornerback Kevin Johnson.The people spoke on condition of anonymity because the signings won’t be official until the NFL’s new year begins Wednesday.The Bills are coming off a 6-10 season and were left with plenty of salary cap space after spending the past two offseasons purging high-priced and under-achieving talent.The Bills focused their initial attention on upgrading an offense that was a work in progress under rookie starting quarterback Josh Allen last year. Buffalo finished 30th in the NFL in yards gained and featured a patchwork offensive line and an unproven group of receivers.The biggest splash is the addition of Morse.He fills an immediate need in addressing a position that featured a revolving door at center after Eric Wood retired due to a career-ending neck injury. Morse spent his first four seasons in Kansas City, where he started 49 games.Listed at 6-foot-6 and 305 pounds, Morse is expected to provide on- and off-field leadership as well help better protect Allen, who was sacked 28 times in 12 games.Kroft agreed to a three-year contract that will pay him a base salary of $6.25 million per season and has a potential value of $21 million, one person said. He spent his first four years with Cincinnati and fills an immediate need on a Buffalo roster that currently features one tight end Vincent Taylor Jersey , Jason Croom.A foot injury limited Kroft to four catches for 36 yards in just five games with the Bengals last season. He enjoyed a career year in 2017, when he had 42 catches for 404 yards and seven touchdowns.Another person said Gore agreed to a one-year, $2 million contract. He is the NFL’s active leader in yards rushing and returns for a 15th season after spending last year with Miami.He continues to be productive after finishing with 156 carries for 722 yards and no touchdowns in 14 games with the Dolphins. He added 12 catches for 124 yards and one score.The 35-year-old will join 30-year-old LeSean McCoy in forming what would be the NFL’s oldest — and most historically productive — running back tandem.Gore’s 14,748 yards rushing ranks fourth on the NFL’s career list, while McCoy is 25th with 10,606 yards rushing.The two are close friends, share the same agent and have spent previous offseasons working out together.Gore is also in line to have another connection in Buffalo, after the University at Buffalo extended an offer to his son Albert Wilson Jersey , Frank Jr., to play for the Mid-American Conference school last month.A third person said Johnson agreed to sign with Buffalo four days after making the Bills the first team he visited after being cut by the Houston Texans. He will compete for the starting job opposite Tre’Davious White.The 26-year-old Johnson was selected by Houston in the first round of the 2015 draft but never played to expectations because of injuries.He was limited to playing in only the Texans’ season opener last year. He was placed on injured reserve after his second concussion of the summer. A broken foot and sprained knee limited him to a combined 18 games from 2016-17.Overall, Johnson has one interception in 35 games, including 18 starts. The Dolphins used rookie defensive back Minkah Fitzpatrick at three different positions in 2018. He’d like to narrow that to one in 2019, and he’d like to know fairly soon which one it will be.Via Barry Jackson of the , Fitzpatrick said late in the 2018 season that he’d like to have an answer by January or February. And Fitzpatrick has a practical reason for knowing the answer.“I lost 10 pounds playing cornerback because I moved faster, chasing guys around,” Fitzpatrick told Jackson. “If I鈥檓 playing safety Robert Quinn Jersey , maybe eight to 10 pounds more [is better] so I have a little extra thud.”Fitzpatrick made those comments before a majorthud happened in Miami, in the form of a coaching change. With Patriots linebackers coach Brian Flores expected to take over, he’ll likely be the one to decide where Fitzpatrick plays: Safety, slot corner, or boundary corner.
