Between a few big trades and a flurry of activity among the players who did reach free agency, there were opportunities for aggressive teams to improve. And some teams took some hits with players leaving.

The Pittsburgh Steelers have been the most frugal team in free agency, spending just over $22.9 million, per OverTheCap. They have been more active in the trade market, adding DK Metcalf from Seattle and extending him on a deal that will cost $30 million per year on average.
