Comcast SportsNet Mid-Atlantic will launch a daily talk show patterned after NBC’s “Sports-Talk” brand. “SportsTalk Live” debuts at 10:30 p.m. Jan. 23, with a logo, branding, graphics and music that mirror “NBC SportsTalk,” which is carried on NBC Sports Network. The set also will look the same. NBC Sports Chairman Mark Lazarus described the half-hour show as a test, and said he expects other Comcast regional sports networks to roll it out eventually. It’s not clear when other markets will launch their own versions. The local shows will not necessarily mirror the national show, which consists of former CSN Mid-Atlantic anchor Russ Thaler anchoring a news-based 30 minutes. Rather, “SportsTalk Live” will feature more opinions and debate, network executives said. Network executives would not compare the new show with other ones, but it sounds similar to a cross between ESPN’s popular “Pardon the Interruption” and “NBC SportsTalk.” Former Washington Redskin Brian Mitchell and former Washington Post staff writer Ivan Carter will host the show, which essentially takes the place of “Washington Post Live,” which ended its five-year run on the network last month. It will focus on Mitchell’s and Carter’s opinions and debate. Unlike “Washington Post Live,” the show will not have many outside guests. When it uses guests, it will rely on the CSN reporters, as well as on-air talent on NBC’s other sports channels, reported by SportsBusiness Journal.
