You know, since we've brought up many past and present sports announcers who would be great GS hosts...
WHERE IS JIM McKAY?!?!?!?! Or Al Michaels, Pat Summerall, James Brown (no, not that James Brown), or Verne Lundquist?
Summerall may be calling NFL games for ESPN until Mike Patrick (their main play-by-play guy) returns to full strength after surgery, but he's slow as hell! JB could do an adequate job; ditto for Michaels. And Lundquist may provide a witty style similar to J.C. Daly.
