"We're trying to make big plays on defense, and we've done that, " Harper said. "We scored twice this week (on interception returns against Miami) and set up the offense for another one. It's always good when you can do that for our offense.

"(This system) allows me to do what I do best. I can fly around. I don't have to do a lot of thinking, a lot of doing too much. We have roles, and it puts a lot of freedom on us. We have different calls that Gregg allows us to make within each play call, and it allows us to cut it loose, and we're doing that right now.

"We're just running around. I think that's what it is. He doesn't try to put so much emphasis on X's and O's. As long as you're running hard -- playing fast and playing hard -- that's what he wants to see more than anything.
"A lack of effort is just a 'coward.' He'll call you every word in the book if you show a lack of effort. (But) it doesn't matter if you know what you're doing or not, he'll take the blame for that if you play fast and play his way. Then, the rest is on him. He'll get you lined up, he'll get you in a decent call and allow us to go out there and do what we need to do."
