I agree with others who said Addai looked better in the 2nd half and with those who said his numbers were largely due to the continued emergence of the Colts' offense and a poor performance by a banged up Texans' defense. My only point of contention, and this is purely my opinion, is that Addai hasn't looked the same to me since his injury. Even though he didn't put up big numbers in the first few games behind a patchwork offensive line, I thought he ran well and often eluded several defenders in the backfield to get a few yards. The Minnesota game is a good example. Since his hamstring injury, he hasn't seemed to have the same explosiveness. Even in the Houston game, there were times when I expected him to explode through a crease or turn a run upfield, but he seemed reluctant to kick it into that next gear. I couldn't even guess as to whether he's not totally healthy yet, or just doesn't yet trust that he's healthy, but something is missing. Perhaps he's working his way back from his hamstring injury in a way reminiscent of Ryan Grant, who is only returning to form months after sustaining the injury.
This is just my opinion, and I can't back it up. Certainly, I can't argue with the production, and his schedule down the stretch is mighty fine, so he's still a great guy to start from this point forward. I'll add that the Colts' offense continues to progress as everyone gets healthy, and they should post some big numbers during the fantasy playoffs. Sunday in the 2nd half was the first time this season I've felt confident every drive that the Colts would get at least a TD unless something odd happened (e.g. dropped pass, holding penalties, running out the clock).
