He blamed himself, saying that he rushed it despite a perfect defensive situation:“Just trying to out it on his body low before that while player got there. If I could put it on his body, he can catch it, take the hit, and get into the endzone.”However, he insisted that despite mistakes like it, the Chiefs were starting to grow into each other as a team:“I mean, we deal with adversity. It's about how you deal with it. And obviously this isn't how we want to start, but how are we going to respond? ...It's not like we're missing by much. I know it sucks for fans, but I feel like we're close. And so all we can do is just continue to work and continue to get after it and be ready.”Meanwhile, head coach Andy Reid took full responsibility for the loss, while still discouraging his players from being demotivated:“Keep playing hard. I’ll take this one, you keep playing hard. Stick together, play hard.”The Chiefs' next game will be a visit to the New York Giants a week from now. Kickoff is at 8:20 pm ET on NBC.
