The Cardinals are signing former Chargers defensive tackle Darius Philon to a two-year, $10MM deal (Twitter link via Tom Pelissero and Ian Rapoport of NFL.com). Philon will receive $5MM fully guaranteed and can earn a maximum of $12MM through incentives. 
Philon, 25, has appeared in 54 career games since entering the league as a sixth-round pick in 2015. Over the last two years, he’s taken a big step forward in his career. In 2017, he notched a career high 4.5 sacks, playing mostly as a reserve. Last year, he started in 13 of his 16 games and notched four sacks plus 33 tackles overall.
The advanced metrics at Pro Football Focus indicate that 2018 was Philon’s best season yet. He could have an opportunity to build on that as a key contributor in Arizona.
He has definitely improved. Sorry to see him go. We are woefully thin on the d-line and this doesn’t help.
Colts should have signed him.
