WFME will very likely be involved in this, but IMHO 94.7 will not be the ultimate destination of ESPN-FM. I see scenarios on this thread involving WBAI, WPAT and WPLJ, all full-market class Bs.
Not long ago, it was rumored WFAN would simulcast on 660 AM and 92.3 FM. CBS then transferred Rick Gillette from their Phoenix cluster to become PD at 92.3 NOW-FM. CBS wasn't expecting these events any more than any of us who post on this board. If ESPN-FM ends up on a class B ESB stick, CBS' plans for 92.3 will change quickly. CBS will not be able to stand pat with WFAN on 660 AM. Rick Gillette better not unpack yet. He might soon be on his way back to Phoenix!
