The Houston Rockets are preparing a maximum-contract offer sheet worth $55 million over four years for Memphis Grizzlies center Marc Gasol, according to several media reports.

Griz owner Michael Heisley expressed his reluctance to negotiate Gasol's contract in the media Sunday afternoon so he responded with an economy of words.

"We'd match that," said Heisley, who would have three days to make good on his word under NBA rules.
