I would not say Myers and Runyan played spectacularly, but definitely performed above expectation, and (Runyan at least) above average.

Doubs night was one of the most efficient in NFL history.

He caught all six targets and averaged 25.2 yards per catch. The performance is one of the most efficient by a wide receiver in modern NFL playoff history — Doubs is just the 10th player to produce 150 or more receiving yards on six or fewer catches in the postseason.
