‘The case for Hockenson: It’s unfair to call any player the “next Rob Gronkowski,” but the Iowa tight end shows elite ability to make plays down the seam and should be one of the better blocking tight ends in the league right away. At 6-foot-4 3/4 and 251 pounds, he ran 4.70 seconds in the 40-yard dash, the same time as Eagles Pro Bowler Zach Ertz. Gronkowski ran roughly the same (a hand-timed 4.68) entering the 2010 draft. The 6-6, 258-pound Gronkowski is a tad bigger (his arm length is 34 1/4 vs. 32 1/4 for Hockenson). NFL Network analyst Daniel Jeremiah said Jason Witten, Dallas’ 11-time Pro Bowler, is a better comparison.’
