While statistics don't paint the entire picture for receivers, it is a good place to start.
During the 2011 season, Hakeem Nicks and Victor Cruz combined for 158 receptions, 2,728 yards and 16 touchdowns. On the other hand, Rob Gronkowski and Aaron Hernandez combined for 169 receptions, 2,237 yards and 24 touchdowns.
In the playoffs, Nicks and Cruz have totaled 35 receptions, 579 yards and four touchdowns in three games. Gronkowski and Hernandez have 26 receptions, 353 yards and four touchdowns in only two games.
When comparing these two duos, the statistics are rather close in both the postseason and the regular season. What ultimately gives Gronkowski and Hernandez the advantage in this area is their ability to score touchdowns.
Those two have combined for 28 touchdowns in the regular season and postseason, compared to 20 touchdowns for Cruz and Nicks. They've also done it in one less game than the New York Giants' receiving duo.
