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.
  

BET executives have been working hard on defending Lil' Kim's (real name: Kimbery Jones) new reality show, Lil' Kim: Countdown to Lockdown. Lil' Kim recently got into some trouble with the law regarding a shootout between her friends and some rivals. She was sentenced to some jailtime (a year and a day) and this reality series, premiering March 9, will follow her as she prepares for her time away (recording some music, doing a video, caring for her family, etc.). The executives have been insisting that the situation and subject will not be taken lightly and that the series is a chance for the rap star to reveal herself (um... emotionally). It's probably just me, but I always find it a little hard to take something completely seriously when it has any sort of wordplay in the title...
