We’ve already tackled the draft and free agency, but there is one more facet of the IDP offseason that could potentially play the biggest role in altering a player’s value: scheme changes. When a team brings in a new Head Coach or coordinator, it’s a good bet that the new guy will want to imprint his own style on the team he’s inheriting. And while only seven teams changed their Head Coach since the 2014 season, a whopping 12 changed their Defensive Coordinators. Not all of these personnel changes will result in a true scheme change, but they all figure to have an effect on the opportunities presented to IDPs. It may take until training camp and the preseason to get a read on some situations, but there are other teams where we can already sense how things will look in Week One.
