Nobody expected perfection from the Bucks defense so early in the season. The loss of Jared Dudley and Zaza Pachulia lowered expectations in the first several months for a team still boasting a defensive identity, but a league-worst effort through the first 15% of the regular season? That wasn't part of the plan.
Uncontained penetration, wide open threes and early fouls have plagued the Bucks defense in early play. Are these issues a matter of personnel -- swapping out Pachulia for Greg Monroe and Dudley for Jabari Parker -- or is there something deeper at work?
