Monroe provides no interior defense so finding another big to pair with him is a real problem because he is also a traditional low post player. If you want both interior defense and proper floor spacing, you have to find a rim protector with outside shooting range. These guys don't grow on trees. Remember that Monroe/Drummond was a total fail. The alternative is to start Monroe with Crowder, Middleton, Bradley, and Thomas and count on superior perimeter defense and no interior defense.
