That was the problem with this Test pitch. There was too much grass coverage meaning the pitch was always going to hold together. When the rains came, it ended any chance of the pitch deteriorating.
There was bugger all on this one compared to other years....the commentators all mentioned at the toss that they were surprised he took so much grass off it. The drop in pitches just do not fall to bits because they are prepared and then packed into the ground in trays. The solil cannot loosen naturally like the old MCG pitches did. They also don't have a whole winter of blokes running across them digging them up. Curators can grow these things for months and have deeper root systems that also help hold them together
