Legendary and eventual Hall of Fame tight end Rob Gronkowski has announced his retirement from the NFL.
In doing so, Tom Brady, the New England Patriots and the NFL will inherit a void that may never be filled.
Gronkowski isn't just the greatest tight end ever, he was the most dominant pass catcher of this decade.
Sure, the sheer consistency of Antonio Brown, or spectacular outside-the-numbers dominance by Julio Jones on the outside will put their names in that discussion. They oughta be. But no receiving threat was as uncoverabale as Gronkowski.
