Isiah, when you meet with Donnie Walsh today, tomorrow, Saturday, whenever, I would drop the 1973 stuff when explaining your abysmal four-year record.

Thomas has made the point before but he made it distastefully last night in talking about the “unique problems’’ in trying to win in New York, demonstrated by the Knicks not having won the title since 1973.

“You haven’t been proud here since 1973,’’ Thomas said. “That’s a fact…You haven’t won here since 1973.’’

“You’’ apparently meant New Yorkers. Isiah is far from that – Chicago-bred, Piston-trained.

Forget the Yankees and their record number of world championships. Forget the Giants winning it all a couple of months ago.

This is a fact, Isiah. Walsh will be turned off if you repeat that theme to him. Walsh’s Pacers never won it all, which by Isiah logic means Walsh has never made the Pacers fans “proud’’ of that franchise in Donnie’s 24 years there.

The 1990’s was a very “proud’’ time for the Knick franchise and often Patrick Ewing’s Knicks battled Walsh’s Pacers in wonderful playoff battles. Two days ago, Isiah was treated like royalty at The Palace when they celebrated the franchise’s 50th anniversary. Isiah was probably still stuck in that moment last night, as the face of two championships.

Those two Pistons’ titles mean nothing here, Isiah. Nothing. You are a smart guy. Play to your audience like you did in your rousing speech in Detroit. Walsh doesn’t want to hear about 1973. Walsh wants to know how you destroyed his hometown team and made fans pang for the 1990’s when they were proud and not embarrassed to be Knick fans.
