I agree with you and I think that's what it is.
Problem is. Why give Grier and McDaniel an extra year and at the same time handcuff them in what they can do in that year ?
If Ross doesn't trust them fully, he might as well fire them at the end of last season, if he does trust them then why limit what they can do and set them up with failure with restrictions on who to resign, who to add, cut and draft.
At some point Grier and McDaniel can se the writing in the wall and do a half ass job, collecting paycheck and not looking after improving the roster and team.
But this seems very Ross like
.not fully commiting and putting both feet in the hot tub.
