According to Pro Football Focus (subscription), the Indianapolis Colts have the NFL’s 5th best linebacker unit entering the 2020 season:
5. INDIANAPOLIS COLTS
The Colts have one of the better linebacker groups in the league, led by Darius Leonard, who has been going in the second round of the 2018 NFL Draft. Leonard has the sixth-ranked grade among linebackers over the past two years and has missed just 5.6% of his tackles, good for seventh-best. A true three-down linebacker, Leonard has graded well in all phases, and his length has fit well in the Colts’ zone-heavy scheme.
