For numerous reasons the D has a lot of young guys playing a significant number of snaps.
Something many on this board have been harping about for years.
Right now, there is some pain because of it. If it ends up growing pain, everything later in the year will be much better.
If these young guys don't improve.............not so much.
Right now, with all things considered, I'm pretty excited to see how the D plays the 2nd half of the season.
