I don't know. I'd have to go look.
The last nine DBs we drafted were 2016 CB Anthony Brown (6th round, played in 6 games), S Kavon Frazier (6th round, 0 games); 2015 CB/FS Byron Jones (1st round, 22 games); 2014 DB Ahmad Dixon (7th round, 11 games), DB Terrance Mitchell (7th round, 8 games), 2013 DB JJ Wilcox (3rd round, 51 games), CB B.W. Webb (4th round, 39 games), 2012 CB Morris Claiborne (1st round, 46 games), DB Matt Johnson (4th round, 0 games).
The last seven DBs Philly drafted were 2016 CB Blake Countess (6th round, hasn't played), FS Jalen Mills (7th round, played in 6 games); 2015 CB Eric Rowe (2nd round, 18 games), CB Jacorey Shepherd (6th round, 1 game), CB Randall Evans (6th round, 1 game); 2014 DB Jaylen Watkins (4th round, 14 games), CB Ed Reynolds (5th round, 7 games); 2013 DB Eric Wolff (5th round, 18 games), DB Jordan Poyer (7th round, 48 games)
So we have two starters and two backups remaining from our last nine DB picks, but the starters are both first-round picks.
The Eagles have two backups from their last nine DB picks, but have generally taken them lower than we have.
Of course, there are other factors as well, such as the Eagles having changed coaches this year. Overall, though, our DB draft picks have appeared in 183 games while the Eagles' picks have appeared in 113.
I went back to when we got Claiborne, so it wasn't completely random. It also would have been better to compare Dallas with another team with a steady head coach situation.
