Over the past few seasons, the Texans' playing surface has become a much maligned topic. The trays or pallets of natural grass that they had been using for the had begun to deteriorate and were displaying visible signs of decay. Issues then began to arise with the various teams which visted NRG stadium with many complaining about the surface itself. Per ESPN's Tania Ganguli :
Over the years players and coaches have expressed their frustration with the surface. Patriots coach Bill Belichick did so after then-Patriots receiver Wes Welker tore his anterior cruciate ligament on it. Eagles players complained about the field after then-Eagles linebacker DeMeco Ryans tore his Achilles tendon on the field. It was the second time Ryans had torn his Achilles tendon on the same field. After Texans linebacker Jadeveon Clowney suffered a lateral meniscus tear, then-Texans safety D.J. Swearinger told NFL Network that Clowney had stepped in "one of the holes" on the field.
This issue was quickly remedied at the beginning of last season, when the Texans replaced the pallets with synthetic turf. This year, the Texans will be using new UBU series turf at NRG sSadium.
It's so shiny.
