"I don't have a system," explains Sister Marie Louise, 89, a Washington nun who has won national attention by her uncannily accurate picks of the winners of National Football League games. "I read the newspapers. If I get a hunch, I stick with it. Of course, I do pray and ask the Holy Spirit for help." That seems to work divinely. On a local TV program that asks guests for N.F.L. predictions, the Visitation nun, who once played basketball and baseball, has so far bested the secular guessers. Along with the mother superior, a fellow football fan, the sister follows the sport on the convent TV. Has she made a pick for the Super Bowl? Only heaven knows.
