While Gronkowski brings his own unique style, it’s Hernandez that’s the offensive hybrid every other team in the league now covets. “He’s the x factor that makes the Patriots offense hard to match up with from a personnel standpoint,” Sam Monson, an analyst for Pro Football Focus, said of Hernandez. “Gronkowski is a nightmare too, but in the same way any great tight end is always tough to defend. Hernandez forces teams to make a decision about whether to treat him as a wide receiver or part of the run game before the huddle, and that tends to change personnel groupings on defense.”
