Kevin Garnett supposedly has guaranteed that the Celtics win the title the next two years.

Garnett expressed optimism in a recent conversation with team owner Wyc Grousbeck, who spoke yesterday at a corporate sponsorship event at the Boston Harbor Hotel. “I talked to [Garnett] and he guaranteed the championship in 2010 and in 2011,” Grousbeck said. “He was as fired up as he’s ever been.”

Vince Grzegorek has been with Scene since 2007 and editor-in-chief since 2012. He previously worked at Discount Drug Mart and Texas Roadhouse.
