The Pittsburgh Tribune-Review reports on the development of a football play analysis technology that helped coaches at the high school in Bellevue, Wash., prepare for a major upset of the nation’s No. 1 team from Concord, Calif. The Landro Play Analyzer grew out of its creator’s research for a master’s degree. Originally developed as a classroom teaching technology, the database-driven software archives video and is popular with football coaches, because it can store up to 20,000 plays for instant playback.
