Butch Metzger is neither the answer to #7 nor a beloved backup catcher, except possibly in the sense that ...
if a relentless but localized parasitic infection ravaged the 1978 Mets dugout,
in the first game of a double header,
leaving only those safely ensconced in the bullpen disease free,
and they had to form a lineup for Game Two comprised entirely of relievers,
because even the backup catchers left the bullpen to pinch-hit at some point,
passing through the dugout to grab a bat from the rack,
before they realized the danger that was upon them,
and so somebody had to catch Game Two,
and Metzger was of less value and therefore more worthy of risk than Dale Murray or Bobby Myrick or somebody.
... then sure, in that sense he can be called a "Beloved Backup Catcher," as he was probably beloved by somebody, even if that sort of logical stretch makes for a massive violation of the spirit of the question.
But no, that is not the answer.
