First FM sports station in town? 102.9 was a KJR-AM simulcast in the early 2010s, after they flipped from KNBQ Q Country. Not saying it isn't plausible that sports will be the new format.
Hispanic...nah. This isn't Yakima. Seattle already has 102.9 and 99.3 (and the latter has 3-4 boosters either operating or on CPs to serve South King County where most of them live, can't remember).
Don't count out 'Alt 93.3' either. iHeart will often flip stations for the benefit of clearing national morning shows...like Bobby Bones. iHeart would love to clear The Woody Show in another big market.
Simulcasting Black Information Net. - not a chance in hell. Watch them drop to a 0.1 share.
I'd say the chances are also slim...but why not Rhythmic *Oldies* leaning 1970s-90s (ala the old Mega 99.3 in Yakima before they tweaked to classic hits), to compete with KHTP and take some of the rhythmic/Black audience away from their co-owned 'Jet'? Brick, Stevie Wonder, The Commodores, Aretha Franklin, Earth, Wind and Fire, some Michael Jackson, Bobby Brown, En Vogue, etc.? But maybe the demographics don't match for good potential. Like their co-owned Hot 95.1 in Albuquerque, or Jammin' 101.5 serving Denver.
