Except the regression is this year only... last year was the best results this group has had, in any measurable way.
Some of it is no fault of anyone, just time... Tavares, Brodie, Giordano have all declined at a very rapid rate. Tavares I'm not ready to count out, his play is still strong, he's just not getting results... which often does trend back to a norm... unless that little bit of a lost step has killed him, which we'll know over a longer time period.
Some of this is just Tre's mistakes. We had a solid defensive team, even if the depth scoring wasn't there. Now our team D has suffered, and we are actually worse at depth scoring. His signings, except Benoit have largely been disappointing, though I don't have an issue with Domi's production for his dollars. (Though Domi only has 2 points in the last 12 games).
I don't dislike Keefe, but there is a lack of sharpness to this team, that perhaps a new coaching voice can change... or maybe the players aren't coachable, or aren't winners. I think that coaching change should be made now.
It might also be time for a complete purge in the front office... Shanahan down... it's been a decade and it's not working. That's enough time. Some fresh eyes are needed, to determine which of the core just doesn't have it to compete and win. That's the important thing, finding solutions, not necessarily which GM is to blame..
