As Dan said himself, he hasn't played organized baseball beyond Little League, so while he's a fan of the game, he has no actual experience playing. For a color analyst, that is the real reason to have them around at all.
I assume they're waiting on legal to hammer out a deal with FP to get rid of him, and once that's done, maybe they can find someone. It is tough mid-season though, and with them axing so many in the off-season, there isn't a Bo Porter or Ray Knight (Ray was horrible when he filled in for Dibble and FP) that they can just plug into the spot.
