Almost five years after Charlie Weis nearly died, he faces the prospect of every detail of his long battle with obesity and his bypass ordeal becoming public record as he goes to trial next month in Suffolk Superior Court in his medical malpractice suit against two Mass. General physicians. With Patriots quarterback Tom Brady expected to appear as a star witness, the case could draw national attention as Weis tries to prove that the doctors -- Charles M. Ferguson and Richard A. Hodin -- acted negligently in leaving him so close to death that he received the Catholic sacrament of last rites. Weis has altered Notre Dame's spring football schedule to accommodate the trial, which is slated to begin Feb. 12. "It was probably the biggest mistake of my life," he wrote of undergoing the procedure in his recent book, "No Excuses: One Man's Incredible Rise Through the NFL to Head Coach of Notre Dame." Weis, 50, who declined a request for an interview, described himself in the book as "a dumb ass" for submitting to the weight loss surgery.
