At some point, a given offensive fantasy football sleeper runs out of chances to realize his potential. Such a timeline usually incorporates 2-3 seasons and if a breakthrough is not reached in that span, this player becomes largely dismissed by the fantasy community as a whole. We could very well be reaching that point now with Philadelphia Eagles tight end Zach Ertz who is currently battling a hamstring injury and who for the third season in a row is letting those down who drafted him thinking a breakthrough was imminent. The breakthrough hope was an understandable one as Ertz has shown flashes of big-time receiving ability but who ultimately has been a letdown as whole both in 2014, 2015, and now 2016. Expected to sit out Week 11 with the hammy, Ertz now sits with just 29 catche for 302 yards and 0 scores this season despite the fact the Eagles have gone with a rookie under center in Carson Wentz from the start. With rookie tight ends often looking to their tight ends as an outlet, Ertz' lack of production is even more shocking. So with Ertz now injured to go with a lack of receptions, it is no time to drop him in all formats and to stop hunting down potential that he just carry anymore.
