Here's some "TV News" scoop from next week's issue of TV Guide magazine (on sale Monday): Snoop Dogg has been cast as Omar Gooding's older, wiser, less doped-up sib Big E on ESPN's pigskin soap Playmakers. Snoop appears in the Oct. 28 episode, and should the sports channel renew the serial for a second season, bet on the Doggy Fizzle Televizzle emcee to reprizzle da role. (That's for critics who say this column's not ghetto enough. Word.)
