Three distinct developments are, uh, developing in the wake of Sunday night’s Lincoln High–versus–Boys and Girls High postgame brawl (riot cops! 21 arrests! girls whaling on boys!) outside Madison Square Garden. In the first move, Garden management says it may refuse to host high-school basketball championships in the future. In the second, spooked school officials propose moving the big games from the evening to the afternoon. And in the third, CBS has announced its purchase of MaxPreps, an online sports network that tracks 500,000 high-school basketball games each year. Presumably because they don’t want to have to sue you for using YouTube the next time.
