Things are really starting to heat up on the networks this week as seven new shows grace the schedule. Most notable, Dennis Haysbert returns to television in The Unit, which is produced by genius playwright David Mamet. ABC also launches its new part-scripted, part-improvised comedy, Brothers and Sisters, and the race-swapping reality show, Black.White, makes its debut on FX. Oh, and Lil' Kim gets her last 15 minutes of fame before going to the slammer.

• Pros Vs. Joes, Mondays @ 10pm on Spike (premieres March 6)
• Ordinary people face off against pro athletes like Karl Malone, Bo Jackson, Jerry Rice, Jennie Finch, etc. This is for sports fans with big mouths.

• The Unit, Tuesdays @ 9 on CBS (premieres March 7)
• Dennis Haysbert returns to action-packed television, this time as the leader of a special ops team that goes on risky missions across the globe. The show is about the missions, but also about how the families at home handle the stress of living in secret. Produced by David Mamet.
