At the very least they need to improve their depth at C. Giannis and Bobby Portis have essentially been playing C since Lopez went down after the 1st game and Portis has missed 5 games himself as well with Giannis missing one. Giannis is the best help defender in the league and it takes away from what he can do defensively when he plays center . Up until this early season injury Bug the Bucks have been pretty healthy under Coach Bud , the long title run too include long series against the Nets , Hawks and Suns probably didn't allow them to come into the fully healthy. Giannis is Mutant so he is the one that held up the best among their Corps of stars.
