Zach Ertz's Instant Fantasy Reaction Heading into 2013 Fantasy Playoffs

Zach Ertz picked the best possible time to impress fantasy football managers, but don't expect him to remain relevant.       

The first-year tight end, who entered Week 13 with 274 receiving yards and one score, compiled five receptions for 68 yards and two scores in the Eagles 24-21 win against the Arizona Cardinals. Per the Philadelphia Eagles' official Twitter page, the two scores is a notable feat for the rookie tight end.

Chances are few fantasy owners are reaping the rewards of Ertz's breakthrough performance. He's the No. 2 tight end in an offense has not utilized starter Brent Celek much either.    

Some managers looking for a streaky tight end for their postseason run may now want to ride the hot hand in Ertz, but don't read too much into one strong game.

Rather than establishing Ertz's merit, this merely tacks onto Arizona's status as a golden matchup for opposing tight ends. Heading into Week 13, the Cardinals allowed an NFL-worst 13.7 points against tight ends by ESPN's scoring. 

That number will only rise after allowing two scores to Ertz and one to Celek. The takeaway here is to pursue Jared Cook, Delanie Walker (if healthy) and Zach Miller in upcoming weeks when Arizona pops up on the schedule during the fantasy postseason.
