That's not just a far-fetched page out of Don King's hype book; of all great tight ends in history, Gronkowski is the most freakishly physical at 6-foot-6 and 265 pounds. Chancellor was described by one teammate as an "animal, beast, anything that eats mammals."
This bone-jarring matchup merits a closer look:
Seattle's leader and tone-setter
Chancellor is the lifeblood of a team that is at once the NFL's most physical and most philosophical, head-hunting while inspiring teammates to brotherly love.
"We're some bad men when he comes," Sherman said. "He just brings that menacing force. We're a pack of wild dogs and they're pretty dangerous, but a lion running with a pack of wild dogs, that's something."
Although Chancellor is known primarily for his bone-crunching hits (picture Demaryius Thomasin Super Bowl XLVIII or Mike Tolbertin the Divisional Round of this year's playoffs) and excellent run support, his coverage skills have noticeably improved since returning from a nagging ankle injury in mid-November.
"I've said this several times," Sherman emphasized Thursday, "but he should have been All-Pro this year, first team, and I don't think it was even close."
What makes this matchup so riveting, though, is the sheer physicality.
"We talk about hitting in the strike zone," defensive coordinator Dan Quinn said Wednesday. "Just like when you're throwing your fastball absolutely as hard as you can. We're trying to hit somebody in the strike zone absolutely as hard as we can. And (Chancellor) is our fastball pitcher, for sure. He's our closer, coming in throwing high 90s at the end of the game. He's that one that brings gas."
The NFL's most valuable non-quarterback
Similar to Dan Marino and Eric Dickerson at quarterback and running back, respectively, in the 1980s, Gronkowski has rewritten the early-career expectations for tight ends. Tight ends are no longer compared to Kellen Winslow, Mike Ditka or John Mackey. Gronkowski has broken the mold.
Who has the advantage?
"Epic" and "violent" are two words used by Seattle players this week to paint a picture of the Gronkowski-Chancellor matchup.
"It's going to be loud, I'm sure it's going to be loud," Sherman said. "Two big, strong men -- I think that's what football is about. I think a lot of people are looking forward to that."
That's a major upgrade from their previous five postseason games (including Super Bowl XLVI), which Gronkowski has missed with a high-ankle sprain, a broken forearm and a torn ACL.
The Seahawks have a chance to slow Gronkowski on Sunday. But it's going to take a collective effort featuring Chancellor's size, Sherman's playmaking ability and Thomas' speed.
