I have no idea what this is supposed to mean.
There are teams that don't even have a catcher on their top ~30 prospects list while Toronto has a handful. Moreno's best use to Toronto might very well be as trade bait.
Fangraphs lists:
LAA - zero C
PIT - zero C
SEA - two C
SFG - two C including Bart
CIN - two C including Stephenson
TOR - five C (Kirk, Moreno, Adams, D'Orazio, and McGuire) plus a decent young MLB catcher in Jansen.
