7. Alfred Blue, Houston Texans: After an intriguing preseason, Blue made the most of his chance to fill in for the injured Arian Fosteragainst the Giants. Rumbling for 78 yards at 6.0 yards per pop, it's worth noting that 46 of those yards came on one run. He doesn't give up easily on carries, but Big Blue kept Houston's Blue to 2 or fewer yards on nine of his 13 runs. Still, he deserves credit for stepping up in a pinch.
