It was later found their practice field had a shock pad AND crumb rubber which results in a spongy field.

As mentioned, the crumb rubber is being replace with organic infills which in turn require a shock pad to meet HIC requirements.

New England used both...because they didnt know what they were doing.

Whoa.

You'd figure that softer would be a little better, but yikes.
