It's ok to say "I don't know".
You guys dodged a bullet. DeVante Parker injured his foot in practice Friday night and is seeing Dr. Bob Anderson in Charlotte to get a second opinion on the injury. I hear it's just a sprain but I'll bet he's probably not going to play on Labor Day. In the Russell Athletic Bowl last December he had 9 catches for 142 yards and a TD against your secondary. Word out of camp is he's been borderline uncoverable with the coaching he's gotten from Bobby Petrino. He was primed for a monster season so hopefully he only misses a couple of games.
Luckily if there's one position group that can take a hit like this, it's the WR group. There's plenty of talent behind him in that group but he can't be completely replaced. Your D would have had to roll coverage his way on most plays creating openings for Gerald Christian (TE) down the seam and whomever are in the Z and W spots. Unfortunate but not a killer in any of our games in the first month of the season.
