This is going to shock you, but... the Philadelphia Eagles don’t blitz much. We knew that already, but as Football Outsiders has pointed out, they brought a four-man rush more than any other team in the league last year. There’s several reasons for it; one being their effectiveness at creating pressure without extra help.
“The Eagles were the most frequent user of a four-man rush in 2018 and have been among the leaders each of the last three years. In that time, they have consistently generated pressure without a blitz on about one-third of their opponents’ pass plays.
