The Texans and defensive end Angelo Blackson agreed to a new three-year, $12MM deal, a source tells Adam Caplan of NFL.com (on Twitter). Blackson played in 40% of the team’s defensive snaps last season and emerged as a pleasant surprise for Houston. 
Blackson first joined the Texans in 2017 after spending the previous two seasons with the Titans. He had just nine tackles across nine games in Year One with Houston, but he took on a larger role last year. Appearing in all 16 games (four starts), Blackson amassed 24 tackles, one sack, and three passes defensed. For what it’s worth, Pro Football Focus graded him as just the 99th ranked interior defender out of 112 qualified players.
The Texans still have lots of work to do on the defensive line. Christian Covington, Brandon Dunn, and Joel Heath (RFA) still need to have their contracts addressed.
