From a purely assignment perspective on defense? Not at all. In fact we might be better defensively and a better rebounding team.
I think there is a lot of flexibility with the roster already and with the addition of Thorpe alone there are some answers. A lineup of Howard (Frank or Washington), Thorpe, Battle, Moyer/Brisset, Chukwu/Sidibe can win games in the ACC. If Moyer/Brisset can provide some perimeter offense and play effectively at the 3 Battle plays exclusively at G. If not he fills the SF void leaving a 3 man rotation of combo guards.
Tucker would absolutely solidify things and enable JB to go with a more conventional lineup with set positions. Dolezaj would be an interesting rotational piece but there will be options whatever happens over the next couple of weeks.
My bigger concern is that with the sanctions limiting recruiting and the scramble to complete the '17 class are we falling behind for '18?
