No discussion about touchdowns would be complete without Rob Gronkowski.

Despite averaging only 12.5 games per season, Gronkowski is second in the league in touchdowns over his career (2010-2013) with 42, and is first in the league in red-zone touchdowns in that span with 32.

A whopping 47.8% of Gronk's red zone targets in his career have resulted in touchdowns, 6.4% higher than second place Dez Bryant. The average for players with 50 or more red zone targets since 2010 is 28.9%.

Nobody is more of a lock to put up huge touchdown numbers than a healthy Rob Gronkowski.
