"I felt like I jumped it perfectly," Kalu said, via The Tennessean. "And even then I was just like, 'Please don't let me miss.' And I'm looking at the ball and I hit it with my left hand, and I guess the rest is history."
On the live broadcast it appeared Kalu might have jumped offsides, but senior vice president of officiating Al Riveron noted the ball moved before Kalu blasted across the line.
Teammates on the sidelines were astonished by Kalu's jump.
"I saw a replay of Kalu's get-off on that," quarterback Ryan Tannehill said. "He timed it up perfectly. You couldn't time it up any better. Just an amazing play by our guy there."
Kalu said he felt like he was getting closer and closer to a block on previous attempts.
"So I just went with my intuition. I just went," Kalu said. "It was either I block it or somebody blocks it, or it goes to overtime. And I was like, 'OK, I'm going to jump it. Whatever happens, we'll see what happens. We're going to ride with it.' And that's what I did. I'm not afraid to make big plays."
