At least he’s not going backward. The stress injury to Tim Hardaway Jr.’s lower left leg is taking ample time to heal, but he is making progress, albeit slowly, it seems. Hardaway wasn’t wearing a brace on his left leg as he took jump shots, went through shooting drills and jumped off both legs after Knicks practice on Tuesday. “He’s moving more every day,” coach Jeff Hornacek said. “So we’re just monitoring him more, giving him a little bit of time to see how that stress [injury] — whatever it is — responds when he puts a little weight on it. So it’s a good sign that he’s out there doing that.” The Knicks are 6-6, but have lost three of the last four games, without Hardaway, who was averaging 17.8 points per game. The team has only vaguely described the injury, which has kept Hardaway out since Nov. 29. He is supposed to be reevaluated this week.
