You're standing on my neck
Many excuses are perfectly realistic points to consider. You can't lump them together as if they all have the same validity or lack thereof.
As Nublar already pointed out, this is a brand new coaching staff. We also have some brand new players. Considering how rare it is for either to make both an immediate and lasting impact, and how common it is for success to take time, I don't think you can unequivocally say all excuses need to end.
Not every human is a manipulative, opportunistic, letch... or at least that's what I'm told.
