it will never happen. But it should. Turf has no place in sports, period. When my kids play on fake grass I say a few Our Fathers and Hail Mary's that they don't come down w a destroyed knee.
Back to the owners - they will never, ever, ever agree to to going all natural grass because there are some owners who want to squeeze every last penny out of their stadium - a certain owner down on Route One North - but, that is their right and you can't blame them for trying to turn their stadiums (stadia?) into cash cows. These owners want non-stop revenue and they can more easily churn out the cash with a turf stadium - concerts, monster truck shows, a full season of soccer games, international soccer games, etc., turf doesn't get destroyed, turf doesn't need replacing, patching, etc. Less $ out of guys like Krafty Bob's pockets.
And mind you, most teams in the NFL don't own their stadiums - I think only Krafty Bob, the Redskins, and one or two others actually own the stadium. All of the others are owned by some state or local government or a quasi-public agency - and we all know government is a beast that must be fed to quench its insatiable desire to spend money. Turf vs grass is about equal throughout the league. One thing is true, the government bodies that own Heinz Field, Arrowhead Stadium, and Soldier Field put very little into the upkeep of the grass because those fields look like sh#t come November.
But making as much $ as possible from these stadiums is the goal, player safety be damned...
