There really isn’t a depth chart for the defensive line after the first-string unit because the Bruins are trying out so many guys at different spots. As you know, the starting ends are Datone Jones and Korey Bosworth and the tackles are Brian Price and Jerzy Siewierski. David Carter and Damien Holmes look to provide key depth at tackle and end. Reggie Stokes and Jess Ward were supposed to be backups at the other end and tackle spots, but they’re both injured. Keenan Graham and Iuta Tepa are getting looks at defensive end, and Justin Mann should get in on some plays, too. Andy Keane is battling for tackle time, too.
