By and large, matchup plays and sleepers got fantasy football owners through the first week of the season.
Drew Brees against the Oakland Raiders? Easy. Jordan Matthews against the Cleveland Browns? Too easy. And while nobody would claim to have suggested starting Indianapolis Colts tight end Jack Doyle (the dude led all tight ends in scoring going into Monday), Kansas City Chiefs running back Spencer Ware was a superb sleeper against the San Diego Chargers—he posted 25 points.
This week, it's more of the same, though owners now have more reliable data to use. Rather than completely hinging on last year's results and projections, established data from the first week exists.
