Celtics rookie Marcus Smart has spent the last few days helping to bridge the gap between teens on opposite ends of the Israeli-Palestinian conflict. Smart, along with ex-Celtic Brian Scalabrine and Philadelphia 76ers rookies Joel Embiid and Jerami Grant, were special guests at the Seeds of Peace camp in Otisfield, Maine. The goal of the camp is to bring together kids from conflict zones through open dialogue and games. Smart hosted a basketball clinic yesterday, as rocket fire resumed in Gaza following a cease fire. But he said you’d never know it by looking at the kids in Maine. “When those kids are laughing and playing on the basketball court, they’re not thinking about war. They’re thinking about having fun,” Smart said. “It’s just a good feeling to see those kids smile.” Of the 182 campers, more than half are Israeli and Palestinian. The camp encourages teens to hash out their issues with each other, but Smart said he’s not there to talk politics.
