My 2 cents..
Wbb summed it up pretty good, Walters did some really good things, but many of them didn't see the roster.
We seemed to have luck letting guys on the O line go to other teams for years always having the next guy....but then we seemed to stop drafting for position and drafted best athletes, but didn't always utilize them. This has been a slow process but came to a head this season.
D-line for years we didn't prioritize spending, it has worked, with Willy as our only "prize" we have done this for years, but this year Willy's play fell off, Daughters was good, dependable but not great....and we suffered from it.
Coaching MOS has always had good to great coordinators, some may not like Buck but the guy is a really well liked very good coach, going with Hogan was a miss. Can't sugar coat it, it was miss. Jackson, is a bit of an enigma....what did he do this year....
MOS appeared more stressed and flustered this year...why I feel the loss of guys like Andrew Harris, Biggie, Hardwick etc. that he stated were like coaches actually helped him more than we realize...not only did they both lead in exceptional capacity MOS trusted and had faith in them in assisting. He had full faith in Buck and Buck did tons behind the scenes to help....take all that away and MOS lost too many helping hands. We have leaders but they are not the same.
Miller (sp teams coach) has filled in some of those roles and it would not suprise me in the least to see him continue and develop into a very good coach with expanded roles one day.
I feel MOS without all the between input he was used to get "fumbled" a fair bit this year...I still believe he has some great qualities, but like any human he has weaknesses also...he needs the right guys around him to fill his weaknesses and we didn't give him that this year...
We needed leadership and experience, but it appears this year we went to the well a bit too deep...it was clear the roster management could have used younger arguably more talented guys many times, but we rolled out the veterans....I do I understand the thought process, but as we step back it's clear now some of this thought process hindered the overall betterment of the team.
In closing I believe Walters and Osh can get us out of this, Walters needs to focus on and spend on the lines. Osh needs to be surrounded with great coordinators, and he needs to start to move on as tough as it will be for him from some of his veterans....
