If you watched the Texas Bowl game, you would have seen how torn up the field was. The Texans have enough turf for two and a half football fields. If you noticed at Sundays game pretty much the whole field from sideline to sideline have been replaced. Purely speculating but those trays are outside and surely were wet from rain earlier in week. And heard D-Rob say that the Texans had fans on the field to try and help it dry out. They probably moved the trays out either Thursday night (after Texas Bowl) or Friday and replaced them with the new trays. I think it was just unlucky to have the rain and the bowl game the same week, thus the turf was wet and tore easily. I like the grass and hope they keep it. For the most part all season the field was in good condition IMO>
