Hi Kevin. I'd imagine that the Nets will be bumped to 1130, 970 or occasionally 1190 when there are Devils/Nets conflicts.
When the Mets start up and all 3 "WFAN" teams are playing in April (and the fall/winter teams hope to play into May + June), things get tricky. Also keep in mind that the Knicks or Rangers play into this as well if they both are also playing at the same time in April, May and/or June.
Perhaps WOR-710 could become a player in future scenarios - they did carry the ESPN Radio broadcast of the BCS College Football National Championship Game on Monday 1/7/2013.
In the most unlikely scenario where the Yanks, Mets, Knicks, Nets, Rangers, Devils, Islanders, Rutgers, St. John's + Seton Hall (last three are NCAA basketball) are all playing at the same time ("The Age Of Aquarius: When the moon is in the seventh house and Jupiter aligns with Mars..."), the possible radio lineup may be:
--The "fixed" stations first:
Yankees: WCBS-AM-880
Islanders: WRHU-FM-88.7 (Radio Hofstra)
Seton Hall: WMTR-1250 (in the past WABC-770 - don't know if that's still true)
Rutgers: WOR-710
--The "most likely" stations:
Knicks: WBLS-107.5 (3 games have been "bumped" there this season so far)
Mets: WFAN-AM-660 + FM-101.9
(They've shown no signs of wanting to break the simulcast - yet; this could be an extreme test case, however.
The Mets would have only gotten bumped last June for the Devils if the Devils had played a Game 7 vs. the L.A. Kings in the Stanley Cup Final. A similar situation could arise for the Devils and/or Nets this spring.)
--The "next likely" stations:
Rangers: WEPN-FM-98.7
Devils: WBBR-1130
Nets: WNYM-970 or WLIB-1190 or WWRL-1600 (or highly unlikely: WCBS-FM-101.1)
St. John's: ?? (normally on WBBR-1130; Devils could appear on WNYM-970 + Nets appear on WLIB-1190 to free up WBBR)
(possibly there'd be no St. John's broadcast unless it's a Big East or NCAA Tournament game - they'd likely
find a station to carry the game)
Nothing cast in stone, of course...one never knows which way the broadcast winds may blow. Shuffling amongst the above outlets is not only possible, but likely.
Side note: a few Rangers broadcasts have wound up on additional frequencies in the last few years, those being WWRL-1600 (a couple) and WMCA-570 (once). It's been several years since the Rangers have aired select games on WABC-770.
WWRL broadcasted a few NY Liberty WNBA games years ago.
