Long winded-
That's difficult to answer at this point (and I realize many will disagree with that statement alone).
Generally speaking, I like to see the conclusion of any given season before fully making my mind up about coaches/players. But, this is certainly a unique situation, considering the drastic nature of our season's apparent collapse over the last 3 weeks.
I hesitate to be completely done with Linehan at this moment. If I'm evaluating his fully body of work here, he has done a hell of a job overall, specifically in 2016. You have to imagine in his shoes, he's headed into that season with Romo as his starting QB and without much notice ends up calling plays with a 4th round rookie at the helm who was prepping to be 3rd string. And we ended up with arguably the best offense in the league. There's something to be said for that. And we had a damn good offense this year through the Chiefs game. He also ran a successful offense in Detroit and is well respected (as far as I know) in league circles. I cannot bring myself to wipe everything away for 3 games.
I can't defend Marinelli at this point. We have found a pass rush....a fantastic pass rush in fact, and yet overall our defense has continued to be trash. One middle linebacker - and I don't care how good he is - should not make this big of a difference. We are supposedly a "bend but don't break" defense who keeps plays in front of them, yet we somehow give up enormous "chunk" plays and basically force zero takeaways. Many many posters here, including me, thought that if we found a pass rush our problems would be solved. Not so much.
Garrett, right now, looking like it's the end of the line. HC can't lose the team, and he might be. If, over the next 5 weeks, we continue to go down the toilet Wade Phillips style, he should definitely go. This roster is too talented to get blown out week after week. And it's not just losing. It's being completely uncompetitive and getting crushed.....by teams that aren't even that good. He needs to do something impressive to justify his existence here.
Also, I wouldn't have complained if any combination of our coaches were fired today......but I'm also not overly salty that they're still here.......and that's mainly because, again, I'm not a fan of during-the-season coaching changes.
