Rookies don't often perform big during the playoffs, but Seattle Seahawks wide receiver DK Metcalf is an obvious exception to the rule. His thunderous performance against the Philadelphia Eagles is one of the most memorable postseason debuts in recent memory.

His performance was so good that even Marshawn Lynch couldn't help but be impressed with what the outstanding 22-year-old had to offer. If you ask him what impressed him the most during his performance, he would give out a hilarious response to the question.

“That he a big ass dude who can move like that,” Lynch said, via Pro Football Talk's Charean Williams.

Beast Mode could have used better words to describe Metcalf's performance for the Seahawks, but his words speak the truth. A 6-foot-4 wideout at around 230 pounds usually would find it difficult to move quickly and naturally. However, he managed to do just that. Against the Eagles, he finished with 160 receiving yards and a touchdown on seven receptions. He was easily the best playmaker on the field.

Lynch wasn't the only one impressed with the Mississippi product's showcase so far. Seahawks head coach Pete Carroll also gave out praise to his superb rookie wideout.

“He did some stuff that it’s hard to imagine anyone else doing,” coach Pete Carroll said, via Joe Fann of NBCSportsNorthwest.com. “His confidence is really there. He knows he can play this game at this level. He wants to be in the middle of it all.”

He'll definitely be a key man against the Green Bay Packers, and containing him will be key for Green Bay's success on the field.
