Here's some quick analysis on both of those transactions:
It was a well-known fact that Washington would be aggressive in re-signing its key free agents, but the five-year, $60 million price tag might have pushed the envelope. Gortat was an invaluable part of the the Wizards' success as an effective pick-and-roll partner to John Wall, and a player who could both back up and play alongside Nene. He's also an excellent defensive rebounder, and his mobility up and down the floor made him an ideal target in transition. Re-signing him was a priority for Washington because continuity was a priority for a team that experienced its most successful season in a decade.
I had Gortat valued at four years and $36 million, using Tiago Splitter's deal from last summer as a comp. Splitter is a similarly mobile, rebounding big man, although it bears noting that Splitter is the better defender while Gortat is the superior finisher. The high end of the center market set last summer was Nikola Pekovic 's five-year, $60 million deal, which obviously was the benchmark the Wizards and Gortat's agent went with. Basketball-wise, Pekovic is a better finisher on the interior, and one of the best offensive rebounders in the game, while Gortat is more capable away from the rim and makes his mark on the defensive end.
However, the main distinction between the two players is age: Pekovic was 27 when he inked his deal, while Gortat is 30. For a player so reliant on quickness and speed, you have to wonder whether this contract will be a worthwhile investment in years 3-5, especially if he was signed to a standard, escalating contract that would call for Gortat to be paid approximately $13.6 million in the final year of his deal. With no other team capable of offering a fifth year (or indeed, even offering a deal approaching that average annual value), it seems like the Wizards did a poor job of using the leverage they held to make the last year a team option, partially guaranteed or even wholly unguaranteed.
Golden State was in the market for a backup point guard after struggling with the absence of Jarrett Jack, who left last summer via free agency. The Warriors moved quickly on Livingston, agreeing to terms to a three-year deal worth the full midlevel exception, with a partial guarantee on the last year of the deal. Livingston has successfully reinvented himself after a gruesome knee injury diverted his career path from a preps-to-pro star drawing comparisons to Magic Johnson and Penny Hardaway, to a wily vet and versatile super-sub.
