With Brady Quinn yet to see game action, and Laurence Maroney struggling in his first appearance, the best veteran addition via trade route seems to be backup tight end/fullback Dan Gronkowski. Despite having been with the team for less than a month, Gronk has moved ahead of former second round pick Richard Quinn on the depth chart at tight end, and filled in for injured fullback Spencer Larsen in the last game.
The 25 year old second year pro who goes a solid 6-6, 260, should have a future in Denver. Despite entering the NCAA as a quarterback (and former wide receiver), the second eldest Gronkowski brother became a top blocker as a tight end. He has the requisite size, long (34 1/2") arms, and huge (10 3/4") mitts. As a senior he showed he could catch the ball as well, pulling down 29 passes as Maryland's second leading receiver behind Darrius Heyward-Bey, the top drafted wideout in 2009.
As a perennial Academic All American and Rhodes Sholarship candidate, he has quickly picked up the team's offensive schemes, and he comes with terrific strength (33 reps in college) and surprising speed (4.7 40) for his size. Dan was among the top two or three performers at his postion in every test at the Combine in 2009. Keep an eye on this guy.
