Rams' Sean McVay reveals what he told Matthew Stafford before huge OT pass to Puka Nacua

A 16-yard completion from Matthew Stafford to Puka Nacua in overtime of Sunday's NFC divisional playoff game between the Los Angeles Rams and the Chicago Bears ended up being the biggest play of the night for Los Angeles. 

Facing a third-and-six at the Chicago 43-yard-line, Rams head coach Sean McVay decided to take a timeout after L.A. came to the line of scrimmage, allowing himself to talk to his veteran QB before the biggest play of L.A.'s season. 

In his postgame news conference, McVay revealed what he told Stafford during the timeout. 

What Sean McVay told Matthew Stafford

"We were really talking about what play we liked," McVay said. "They had shown some similar structures defensively and we'd had some success with that particular concept. He did a great job being able to execute it. Just telling what my thoughts were. I changed the play call from what the previous one was and just kind of explained the thought process. He did a great job bringing it to life."
