Allen Park — Will Harris lost count of how many times he's watched the play.
The Detroit Lions rookie safety, in his pro debut last Sunday against the Arizona Cardinals, had one of the game's biggest blunders, allowing himself to be driven too far back by Cardinals linebacker Dennis Gardeck while blocking on a punt.
Gardeck was able to get a hand on Sam Martin's punt in the closing minutes of the fourth quarter, significantly shortening the field Cardinals quarterback Kyler Murray needed to navigate in order to tie the game and send the contest into overtime.
"I looked at it a whole lot, actually," Harris said. "It's one of those things where technique has to come into play a little better. Pretty much, there's a few things I could have done better technique-wise that we talk about here. We're cleaning that up, leaving that and moving on."
Harris is doing his best to leave the stinging moment in the rear-view mirror. The way he puts it, you can't let a mistake from last week beat you this week.
But he is learning from the mistake, putting an added focus on the little things that go into successfully doing his job on that and other plays, so that he'll be able to better execute the next opportunity he gets.
"Obviously, me personally, just being the competitor that I am, I hold that on my shoulders and take full responsibility for anything I'm involved in," Harris said. "That's been the focus this week, trying to get better at all the little things that can build up."
Harris played a team-high 34 special teams snaps against the Cardinals. The Lions also got the rookie safety some experience on defense, running him out there for 15 of the team's 89 defensive snaps.
