Well the D will be better without him. Just need our shooters to show up and keep the defense spread out. UNC isn't some juggernaut they're basically Baylor good this year.
Hoiberg and his assistants burning the midnight oil (even more than they already do) and watching a whole LOT of gametape of both us (our bench/role players) and UNC film.
Find a mismatch. Exploit. Find another mismatch. Exploit. Find our weakness, help cover and minimize it.
I am imagine old Roy and his staff are probably doing the same for his team. Even with losing Niang, I am not sure I would want to face such uncertainty against someone who wants to exploit mismatches.
We're kind of one-dimensional now (Kane). Just like UNC (Paige). We can still see the Sweet 16 after all these years.
My guess is teams pack the lanes with defense now and dare us to shoot from the outside.
