Brown spent the past four years with the New England Patriots after being drafted in the first round of the 2015 NFL draft. He appeared in 60 regular-season games during this stretch, starting 51 of them.
Pro Football Focus provided a breakdown of the tackle's career to this point:
The negative grade likely came from his limited impact in the pass rush. Brown had at least 2.5 sacks and five quarterback hits in each of his first three seasons but didn't get a single sack in 2018, totaling just one quarterback hit.
Still, he was a key player throughout the year for New England, starting in the Super Bowl LIII win over the Los Angeles Rams. It was his second championship in his young career.
Considering he is still just 25 years old, he should continue to improve and potentially gain more consistency going forward.
This will be big for the Saints, who could potentially line Brown up either next to Sheldon Rankins or in place of him after he suffered an Achilles injury last season.
The Saints had the No. 3 offense in the NFL but just the No. 14 defense in 2018, so an improvement on that side of the ball could help bring the team closer to elite status as the squad tries to contend for a championship.
