Sunlight - real grass needs light to grow. Do you build a surface that rolls out (Arizona Cardinals)? Only other option is to design a system of grow lights, Ahhhh…no! Can you imagine the rigging it would take and the setup/teardown each day/night? A complete nightmare scenario for a field management crew. YOU NEED SUNLIGHT FOR NATURAL GRASS. Where do you get it in Detroit…in the Fall…in the Great Lakes region?
Ok…so you build a million dollar track system to move the grass outside the dome cover. Now what? Do you have great weather to grow grass in Detroit, Michigan in November/December? This is not Arizona weather in November. This is Detroit weather
What about a sub-surface drainage system for all of the water? The natural grass needs water. Millions of gallons of water over the season. That water has to go somewhere. How about we rip up Ford Field and put in a drainage system to support natural grass?
Traffic - Ford Field is not just a Football Field. It generates huge dollars from other events. Let’s have 30,000 people trample all over a grass field on Saturday night…just in time to play some football on a Sunday afternoon. The grass will love that. Artificial turf can handle the traffic…natural turf cannot.
The injury rate is not high enough (yet). The NFLPA releases vague/cloudy numbers, but most data I’ve seen (as a field turf manager) is around %1.0 difference in injury between natural and artificial.
The artificial turf has come a looooooong way since the days of Silver Dome turf (I played on it twice and it was brutal - you could barely walk the next day). The artificial surfaces can almost mimic the natural grass. In 10-15 years it will be identical.
The grass isn’t treated within the stadium. It’s done outside then move inside the day before the game. Actually its store outside near the stadium. This has nothing to do with a retractable stadium.
Again it can be done if the lions are willing to spend on the operation. If you can grow weed in a greenhouse then it can be done.
Your right how its done in AZ now explain how your doing that in a foot of snow or couple weeks of sub zero temp . You said green house have you ever been in one with the humidity they keep so high? How about when you wheel the grass thats frozen into the stadium an it turns to a mud pile.
I said before Chubb was playing on grass. Grass likely wouldn’t have stopped the ankle or thigh injuries those happen. Knees maybe turf might cause some. You get rolled up on has nothing to do with turf. GB will play half there games at home on frozen ground same in Ohio teams .
You show facts about grass over turf I will listen but most what is said on this thread , is just repeating what few people X players may think doesn’t make it a fact.
Thompson was injured when Saints left tackle [Trevor Penning]was slung to the ground by defensive end The full force of the 325-pound Penning landed on the back of Shaq Thompson’s leg and ankle.
That had nothing to do with the turf or grass. Shit Happens .
There are several soccer stadiums that have grow light systems. It can be done. Not cheap or easy, but doable.
I guess I don’t really care, since I’m not the one that has to play on ground up tires. But players seem to despise fake turf. If real grass saved one starters knee or achilles per season, it’s probably worth the cost.
There probably won’t ever be a real definitive study of the injury factor of ground tires vs real grass, because most are injuries caused by contact.
It’s possible with a set up like this. Water and drainage could be pretty easily solved too as part of the installation of the surface.
The main issue would be the cost of installation, the ongoing cost of managing the field (all that light won’t come cheap), and the cost of covering and uncovering the grass when there are concerts and other events.
Real Madrid have just installed this cool system, but the cost would be in the tens of millions.
