The current Knicks should show such fight. Charles Oakley, the bruising forward who more than anyone displayed the grit and physical play of Pat Riley’s ’90s Knicks, was arrested and taken out of Madison Square Garden during Wednesday’s game against the Clippers following an altercation with security guards. The incident occurred in the pricey seats after Oakley allegedly heckled team owner James Dolan, who was sitting nearby, said a source who witnessed the incident and asked not to be identified.
