I think Gute is safe. Much easier to rationalize him. Yes there have been some bad picks, but there have been some good ones, and I think he would be firmly in the 10-15 range of drafting if you compared him to peers. He's hit in FA most of the time, unfortunately for him the whiffs were last off-season.
MLF feels like much shakier ground. He's been there a while now. Coaching is more volatile than FO. I personally hope they move on, but another year won't shock me and I think they can rationalize it with all the injuries. I just think his voice, scheme, etc. has gone stale.
