It didn't take long after Kirilenko signed a bargain deal with the Brooklyn Nets for their mini midlevel exception ($3.2 million) for rivals to begin carping about Kirilenko's relationship with Nets owner Mikhail Prokhorov, as reported on Twitter by Grantland's Zach Lowe. It's understandable that Kirilenko would want to play for his countryman, all things equal. Their connection dates back to Kirilenko's days playing with CSKA Moscow, the Russian club Prokhorov supported financially.
Unless additional information surfaces, however, the notion that Kirilenko left a bunch of money on the table to play for the Nets is unjustified. He made a mistake by opting out of the second year of his contract in Minnesota, which would have paid him $10.2 million, but that money was no longer available. The teams with the resources to make a substantial offer to Kirilenko simply went in different directions.
That includes the Spurs, the team most linked with Kirilenko during free agency. I don't know how their talks with Kirilenko went. He may have balked at playing for the non-taxpayer midlevel exception ($5.2 million) or San Antonio may have decided it needed to add multiple players with that money. (The Spurs split their MLE between guard Marco Belinelli and forward Jeff Pendergraph.) I do know that San Antonio could have made a much larger offer than Brooklyn if the team still had its MLE. I also know that the prospect of a Spurs team with Kirilenko flying around off the bench at both forward positions was a scary one for West opponents that will not come to fruition.
