CHARLESTON – As it should come as no shock, Isiah Thomas said his new playbook for this season contains absolutely nothing from Larry Brown’s playbook of a year ago. Thomas, who no longer refers to Brown by name, called his former coach “Einstein” 14 months ago.

Thomas, whose looking to run a motion offense sprinkled in with a high-tempo attack, said it’s the exact playbook he drafted when he coached the Pacers from 2000 to 2003.

“I had my own playbook from when I was coaching, it’s my playbook, I wrote it,’’ Thomas said after Day 4 of camp at the College of Charleston.

When Larry Bird took over as Pacers GM, Thomas took his playbook with him out the door. With Michael Jordan now running Charlotte, Thomas has two rival GMs whom he feuded with during their playing days.

“I want to beat them,’’ Thomas admitted. “Every time we play, see each other, pitching pennies. They may not want to beat me as much as I want to beat them. The way I came into this league, competition is competition. I want to beat them every time I see them.’’

Steve Francis, who arrived at February’s trading deadline, said the team is learning all new plays but said he never really knew Brown’s book anyway. “I didn’t even learn the playbook last year,’’ Francis said. “It changed every day. I couldn’t even tell you.’’

Thomas’ first camp as head coach will be brief and efficient. He has elected to leave a day early, following Saturday’s morning session. However, he will do a handful of two-a-days when the team returns to practice Monday in Westchester.

Thomas’ decision to stay just five days in Charleston is almost half the time Brown stayed here last October when the Knicks went nine days.

“Everything I’ve written down on a piece of paper I wanted to accomplish, we accomplished it and more,’’ Thomas said. “They’re in great condition. I can’t run them any more than I have. You tell them to run through a wall and they say, “How many times?’’

A power outage in downtown Charleston yesterday caused a lack of air-conditioning in the College of Charleston gym that felt sauna-like. Thomas only went two hours and some players complained of the heat.

Best sales pitch in Charleston was a sign in the store window of a men’s clothing store, reading: “Welcome Knicks: check out our big and tall department.’’
