The Bulls are missing Deng. They need to get a good defensive starting 3.
Deng held the team together especially on defense.
That was the Bulls best defensive lineup the past two seasons while Rose was out.
They need to go out and get someone who can replace Deng and start at the 3. Dunleavy is decent but he's hurt. McDermott isn't ready and Mirotic doesn't play defense well enough.
