Each season that canvass is brand new. “What a lot of people don't realize is every spring on Lambeau Field we actually kill off the grass, and remove it mechanically with a machine and we have to grow that back in from seed”, Johnson said. And for good reason, according to Johnson it’s all about the players, “If we let the grass get too mature, and too thick it will be harder for those cleats to break through and sink in where the good footing is. The Packers want those cleats to penetrate the grass canopy and sink down into the sand the synthetic fiber” Without that solid footing there could be more injuries to the athletes.
