Strength of schedule is calculated from the opponents projected fantasy points allowed for the TE position. The best rating is +16 which gives the player the advantage against the defense and indicates an easy opponent, the worst rating is -16 which gives the defense the advantage and indicates a tough opponent.
The Arizona Cardinals offense was an absolute nightmare last year, but even in the middle of that mess Rob Housler still managed to haul in 45 catches for just over 400 yards. The 25-year-old isn’t overly athletic, and he failed to score a touchdown in 2012, so the fantasy upside here is limited. However, Carson Palmer wasn’t shy about throwing to the tight end a season ago in Oakland, so Housler may have some fantasy value as a desperation play or bye week fill-in.
