Well played by Danny.
Despite grumbling from the Smart camp, it was a good idea to wait out the process before putting a real offer on the table. If Danny had said right at the beginning of FA "we have a 4 year, $52 million contract on the table for Marcus," it would have given other teams incentives to make a higher offer just to mess with our cap situation if Danny matched. Alternatively, it would have been a good signal that Danny really values Marcus, and maybe induced another team to revise their opinion of him and outbid us.
By leaving everyone in the dark as to how he valued Smart, until nearly every other team had used their cap space, he basically cut the competition out of the picture.
