Not going to disagree, but I frequently defend Grier when people calim a bad pick is HIS fault. It's not. Grier, by himself makes no picks. And, TBF, Grier can't get credit BY HIMSELF, for a brilliant pick. Credit/blame goes equally to Flo/coaches/scouts.
If might offer a slight difference of opinion:
Good GM's are profoundly influenced by their scouts and coaches (what the coach says they want/need to succeed). From all accounts, Grier works very collaboratively with his staff. That being said, he is the GM, so while he may not have been the only voice in good/bad decisions, it's his JOB to make sure there are no catastrophically bad decisions and that the team makes significantly more good decisions than bad.
So far, I think its hard to judge Grier because we don't have an insiders knowledge of how functional or dysfunctional the brain trust was for the years he's been in charge -- we can only judge the end results, which has been mediocre.
In the negative column, the Gase hire was catastrophic in hind-sight, with knock on impacts in the draft, but we don't know how much the owner (his boss) was involved.
In the plus column, the drafting seems to be trending up, but isn't best of league by any stretch. But his wheeling and dealing to get the team financially healthy and making what would have been hard choices to build a draft pipeline has been top of league. The Flores hire looks very, very good so far.
I'd give him a solid B -- and need to see more improvements with our drafting over the next year or two to remain satisfied (and yes, I know no one here gives a hoot what I think and if anyone on the team read this, they would soil themselves from laughing so hard).
