We're getting deep in the depth charts as big men around the NBA continue to drop like oversized flies. The Lakers are the most obvious example, with Dwight Howard, Pau Gasol and Jordan Hill all going down around the same time.

But L.A. isn't the only team scrambling to find size for its rotation. Cleveland lost center Anderson Varejao, who underwent knee surgery after his efforts at rehabilitating his injury proved to be unsuccessful. He's expected to be out up to and likely beyond next month's trade deadline.

Minnesota's Kevin Love will be out for 8-to-10 weeks after re-fracturing his right hand. Orlando's Glen Davis has a shoulder problem that might keep him out of the Magic's upcoming road trip. Andrew Bynum still hasn't played for Philadelphia, and there remains no timetable for his return. Portland's LaMarcus Aldridge is battling a wrist problem, and his backup Meyers Leonard is out with an ankle injury. Toronto is still playing with its starting frontcourt of Andrea Bargnani and Jonas Valanciunas both sidelined.

We could go on, but you get the idea: It's a bad time to be big. The good news in all this is that we'll get to see some new faces in larger roles for awhile, which also means new names in the Barometer leaderboards. Several of them grace this week's rankings.
