"We've got to find ways to get it corrected. We still control our own destiny. I think they are going to do that [in the future] because that's what they're seeing other teams do.
"It's our job to make sure that we take them out of those coverages. It has to happen, and it has to happen fast. We'll figure it out. I'm looking forward to seeing where we're going from here."
