All of this sounds like normal coach-speak to me. The team's had a hell of an off-season, so they need to be reinforced where they can be. Build up their confidence - but make sure you're correcting the issues seen in practice. Need to make sure they're ready for Nebraska (not that this should be a problem, but neither should Iowa or Purdue) and then PUS.
They've got some key pieces to replace, but should have plenty of talent to do so. As much as I'd love to have Predator back for another year, along with pretty much the entire team, that ain't happening. Maybe this year we're able to have more of a team defense to help disguise where the attack is coming from on D? The offense already spread things around quite nicely - so hopefully that continues.
