The Buffalo Bills will bring in former Tennessee Titans linebacker/second round pick Zach Brown as he will visit the franchise this week. Brown was thought to be a key cog in the Titans' defense, however he turned out to be a little more unreliable than previously thought. The 26-year-old inside linebacker only recorded five starts, 77 combined tackles, 0.5 sacks, three pass defenses and two interceptions in 2015.

In his career with the Titans he has recorded 261 combined tackles, 10 sacks, six interceptions and two forced fumbles. The Bills have had a somewhat quiet offseason thanks to having such little cap space. Before free agency began the Bills were in one of the worst cap situations imaginable and barely had enough space to re-sign any of their players.

They lost outside linebacker Nigel Bradham to the Philadelphia Eagles, cornerback Ron Brooks also to the Eagles, defensive tackles Stefan Charles to the Detroit Lions, tight end MarQueis Gray to the Miami Dolphins, and offensive guard Kraig Urbik also to the Dolphins.

The Bills did make a couple of moves including the additions of strong safety Robert Blanton from the Minnesota Vikings and tight end Jim Dray from the Cleveland Browns. Blanton will come in as a quality depth add for Buffalo as he should line up behind strong safety Aaron Williams if he cannot steal the job.

Blanton is only 26 and can still progress into a more effective player behind a player like Williams. Jim Dray will likely start alongside Charles Clay as they need to solidify their tight ends. Clay was the primary tight end during the 2015 regular season and had some healthy production as Tyrod Taylor's go-to weapon.

With Percy Harvin injured for a large chunk of the season the Bills relied on Clay to become a focal point in the offense. Hopefully Dray will be able to give the passing game a spark with his high motor and solid production. 

The Bills must figure out what they would like to do with the aging Harvin as the wide receiver is a free agent and has shown he is still interested in playing in the NFL. They will also need to address the secondary in the draft considering their former cornerback Leodis McKelvin, who hit free agency at the beginning of the offseason, signed with the Philadelphia Eagles. If the Bills sign Brown they will be adding some key depth into what is already a pretty potent defensive unit.
