(CBS) Much has been made of the Bulls’ recent woes in light of a 121-114 home loss to the lowly Magic on Monday night.

While a 26-13 record still leaves plenty of room for optimism, so much of what Chicago does has been under the microscope after players have openly spoken of their championship aspirations and what it takes to get there. Their performance in losing three of their past four — including two at home to sub-.500 teams in the Jazz and Magic — has been anything but title-worthy.

“We got to decide what we’re going to be,” coach Tom Thibodeau said after Monday’s loss.

One spot Chicago needs to find a rhythm at is with its big man pairings. The Bulls have four capable centers/power forwards in Pau Gasol, Joakim Noah, Taj Gibson and Nikola Mirotic. Yet only so many minutes are available, and Thibodeau’s hinted at ending the Mirotic-at-small forward experiment, so playing time has become even more precious.

In choosing his big men, Thibodeau will take everything into consideration — matchups, health, attitudes, current play, inherent belief and advanced numbers. Only Thibodeau can judge most of that, but here’s at what the statistics say about Chicago’s big man pairings. The list is ordered from the most minutes played together to the least.
