Deep ripping ground with old shallow tile lines?

We've picked up some ground with old clay tile that was put in the ground very shallow decades ago. Places where we've dug up the tile it is completely full with sediment, so I'm not sure it is doing much good. This is rented ground so we don't want to pay to put in systematic tile. The ground is also severely compacted from the previous operator that farmed the ground with intensive tillage. We want to do some deep tillage to breakup the compaction but will likely destroy most of the clay tile that's in the ground. Question is, do we do the deep tillage and destroy the tile in the process or is that going to make things worse by destroying the tile?
