The Boston Globe (Marc Spears) reports: Kevin Garnett’s résumé has a lot more than pro basketball player on it. Garnett worked at Burger King, manned a cash register at a restaurant called Cheers, worked at an Ingles Markets grocery store, and mowed lawns while growing up in South Carolina. He mopped gym floors at a Boys’ and Girls’ Club his senior year in high school in Chicago. But of all the jobs he has held - including playing for the Minnesota Timberwolves - he says his current gig with the Celtics is the least taxing. “Since I’ve been 14, I’ve probably had seven jobs, and since I’ve been working, this is the most rest I’ve ever had in my life,” said the Celtics forward yesterday. “It’s so much that I don’t know what to do with myself. It’s coming at a great time. “You put your heart and soul in this. I’m staying afloat being a vet, being a leader. It’s been good. It’s coming at the right time for this team.”
