Quality over quantity was the rationale.
2013 UFA Additions by Contracts
That approach helps explain why the Rams rank sixth among NFL teams in contractual commitments for unrestricted free agents signed from other teams this offseason despite landing just two of them in Jake Long and Jared Cook.
Maximum potential contract value can be misleading, but in general, the more aggressive teams will commit larger total dollar values toward free agents. As the chart shows, St. Louis ranks relatively high in total dollar values despite signing fewer UFAs than any other team ranked among the top 10.
ESPN.com's John Clayton takes a closer look in his column Sunday. While the Rams focused their UFA resources narrowly, the Arizona Cardinals added a long list of players at relatively low cost. Clayton liked the approach from a value standpoint.
"Three winners emerged from the post-frenzy shopping market -- Arizona, Chicago and Tennessee," Clayton writes. "Based on playing time from last year, I'd give the Cardinals the slight edge from the post-March 17 market."
The chart below, updated from the version published here March 27, lists playing time and contract information for all the UFA players Arizona has signed or re-signed this offseason.
Note: I added Karlos Dansby to the chart below. Most of the additions were unrestricted free agents. Dansby was not. The Miami Dolphins released him.
