I was in the middle of typing a response... but JDB's post is better than mine! So I erased everything I was typing. LOL...
JDB hit the nail on the head- we are replacing 7 starters- but 3-4 of the replacements for this year saw alot of playing time last season. The CBs in particular have extensive PT and experience- which is one of the reasons why our coaching staff has said in an interview that our secondary is the 'strength' of our D right now. The RS frosh CBs even pushed the seniors for the starting CB roles, so we have alot of quality/depth in the secondary this season.
Personally, I'm comfortable/happy with the secondary and depth. I'm also happy with the quality of the LBs- but worried about the depth- hopefully the LBs stay healthy. The question mark for me is the DLine. We have 1 solid returning starter, and 2 players with game experience who are now starters. The DLine has some depth, but its unproven. The coaching staff has said this years D is younger and more athletic/faster than last year, but also smaller/not as strong.
It will be exciting to see how Coach Holt molds this D. I think our D takes a step back from last season, but not a big step. If last season our D was an 8/10...I think this year we are a 6.5-7 out of 10. Still solid and above average.
So, let me understand this correctly - so you're inexperience on D isn't that bad because some of the new players played extensively last year? But, somehow our inexperienced secondary is in deep trouble even though we return our best player in the unit and All-B1G CB, a second kid who started games for us (until he was injured), and our new starting safeties include our regular nickelback and another kid who played extensively?
Got it.
Thank goodness we return almost the rest of our starting defense.
