Patriots' depth tested as backups spark and stumble against Eagles

Patriots win 24-21 in the second preseason game, but depth issues showed up on defense (tackling, edge pressure, and coverage at linebacker), the injury-hit offensive line, and limited early work for some backups. Still, second-year receivers flashed (Kyle Williams and Efton Chism), Lan Larison boosted the third-back spot, Behren Morton served as emergency punter and helped drive the late scoring march, and Andy Borregales was perfect after a rough previous outing, leaving questions about roster depth ahead of the final preseason games.
