Gronkowski is a massive target for the tight end position, possesses a long set of arms and gives quarterbacks a big target to throw to downfield. He's a natural bender for his size who does a nice job sitting into his stance on the line, but it takes him a bit to uncoil and get into his routes. He isn't an explosive, quick-twitch athlete. He's more smooth than fast but showcases a good feel for the pass game and does a great job extending his long arms and plucking the ball away from his frame. He's a strider who possesses only average downfield speed. Gronkowski isn't a guy who can run by NFL linebackers and lacks the speed to drive defenders up the field, but he does a great job selling his routes and is balanced and coordinated when asked to get out of his breaks. He does a nice job keeping his feet under him and exhibits a slight burst, which allows him to consistently gain initial separation. He uses his hands well to fight his way through defenders who want to get physical and does a nice job putting linebackers on his hip and boxing them out of the play. He isn't much of a threat in the open field with the ball in his hands, but he works hard after the catch and showcases the power/toughness to drag defenders and pick up additional yards. Gronkowski showcases the range to reach defenders off his frame and at the second level as a blocker and seal on contact. But he has a tendency to lunge into blocks at the point of attack too often as an in-line guy and will fall off blocks on contact. He has the frame and body control to develop into a good blocker at the next level. He missed all of the 2009 season because of back surgery and will have to check out medically at this year's combine.
