Grass vs. Turf: Time to get real?George Kittle, in attendance at the World Cup final in East Rutherford, N.J., had a message for the NFL:“Grass looks great at MetLife! Can we keep it that way @NFL?? Would appreciate it thanks.”Kittle was one of many stars commenting on artificial turf lately, alongside Caleb Williams, Breece Hall and the players’ union itself:“The temporary installation of natural grass fields for the World Cup is a choice by certain NFL team owners to do for soccer players what they refuse to do for NFL players,” the NFLPA said in a statement on June 10.“It’s no longer a question of capability: the technology exists, the expertise exists and the resources exist to install the high-level grass fields that our players overwhelmingly prefer.”As the battle for grass fields escalates, the lawyer in me can’t resist sharing the arguments for and against switching entirely to grass. But first, a quick look at the league’s 30 fields (remember two of them are home to two teams each):It’s a near-even split, with 16 of 30 using grass (two of which are hybrids made up of 97 percent grass and 3 percent turf), while the other 14 are fully turf.FIFA mandates grass fields for the World Cup, which forced the Cowboys’ AT&T Stadium and Seahawks’ Lumen Field to transform overnight.That should end comments like these from owners:“We don’t think we can have a quality natural grass in our stadium,” said Cowboys executive VP Stephen Jones in 2023, giving a host of reasons for why grass wouldn’t work. Three years (and a successful World Cup) later, we have a video of Dallas staff removing natural grass after the world watched elite competitions being played on it.
