This is going to be a mouthful, but bear with me for a minute.
From 2007 to 2015, there were 180 instances in which a wide receiver or tight end scored fewer than five touchdowns on 70-plus offensive looks (carries plus targets) before managing at least 70 looks the next season. Of those 180 instances, 125 times (69.4 percent) the player scored more touchdowns the next season. Focusing in on the 64 players in that group who scored fewer than three touchdowns during the first season, 56 of them (87.5 percent) scored more touchdowns the next season. Of the 23 who scored either one or zero touchdowns, 22 of them (95.7 percent) found the end zone more often the next season. Jason Avant (2011-12) was the only exception.
