Whenever an NBA team signs a player to a lengthy, multimillion-dollar contract, they automatically hope that the new acquisition will live up to the billing and make the investment look like a good one. Unfortunately, though, that's not always the case.
Deron Williams was the headliner in the 2012 free-agent class, but he's just one of the top 25 free-agent signings we'll be looking at here.
These aren't the 25 best free agents from the class, but rather the 25 players who signed the contracts worth the most over the entirety of their lengths.
If teams had the benefit of hindsight, none of these contracts would have looked the same. Some players turned into huge bargains, while others are already giving their squads a frightful dose of buyer's remorse.
