This Eagles' run defense isn't good, and they have long stretches of absolutely terrible tackling.
The Texans, 1-6-1 and probably the worst team in the NFL, came pretty close. They were tied 14-14 at the half and down only 21-17 when the fourth quarter started.
The Eagle's defense knew Pierce was coming because the Texans don't have much else. But the first-year back from Florida just kept running through them time after time.
