IMHO, it wasn't a "great deadline for us." Semantics about one word, only. I gave it a C at first, did some reading, listening ... then switched to a B ... for basically everything you've said.
Nurkic is still a Blazer. Hope that changes this summer. No big, mobile, defender was brought in -- Not Vanderbilt (PF), not Bamba -- and Drew and Trendon can only do what they can do, and no one should expect the end of the bench bigs to do much except get better someday.
I'll buy the reasoning Cronin gave ... for now. After this summer if not much happens? Not so much.
