Welcome to Beantown, Steph: “Stephon Marbury was wide-eyed and sweaty when he was the last man off the practice floor yesterday…As Marbury spoke, he still was breathing hard even though he’d been on a diligent workout regimen all year. But this was, he was realizing, quite different. This was Celtics abuse. ‘Oh yeah, but it’s good,’ Marbury said, summoning the energy for a brief smile. ‘It was a hard practice today defensively. Defensively this team is amazing. They work at it. They get after it. That’s what it’s about. That’s why they won the championship.’”
