Heck, yes. Brewer's having a good season and would give the Cs some needed SF depth, and Mozgov would help fill what has now become an even bigger area of need (pardon the pun).
At 6-9, Brewer has great length for a SF, and he's averaging 11 points. Pretty good for a third-string 3.
Mozgov brings great size and good rim protection.
And we'd still have Bradley, Lee, and Barbosa at the guard spots.
