Likely the least surprising member of this list, Dez Bryant is one of the most dominant scorers in the league.
Despite missing five games in 2015, no wide receiver has more goal line (from the 10 yard-line and in) receiving touchdowns than Bryant's 15 over the past three seasons, while his 21 red zone receiving touchdowns rank third.
Those lofty numbers come from a marriage of heavy volume and rare efficiency. He has 49 red zone and 33 goal line targets in that three-season span, both top-15 among active wideouts who missed time last season. Among those active receivers, none with 30-plus red zone targets in that span top Bryant's 42.86% touchdown rate, while his 45.45% goal line touchdown rate ranks second among receivers with 20-plus goal line targets.
Even with Bryant and Tony Romo missing significant time last year, the Dallas Cowboys were the third-most pass-heavy red zone team in the league with a 1.93 pass-run ratio, and they were the fourth-most pass-heavy on the goal line, with a 1.82 pass-run ratio.
With touchdowns being such a high-variance stat, it's incredibly rare for someone to show as much consistency as Bryant. It's no stretch to say he's the most dominant red zone receiver in the league, and on an offense that is clearly willing to utilize that skill set, he has huge upside.
