NFL free agency was mostly over before it officially began. The legal tampering period provided an extreme amount of player movement. Most massive deals had been agreed upon by the time the new league year started, and the available options weren't as enticing.
Teams can still find quality players beyond the initial surge of signings, though. Patient squads can pick through the leftovers and find key contributors at a more respectable price.
The Indianapolis Colts, for example, had plenty to spend last offseason. But they waited to maximize their value and did so with the acquisitions of tight end Eric Ebron, cornerback Pierre Desir (re-signed this offseason) and defensive tackle Denico Autry after the first wave subsided.
