I think there’s two sides to it really.
Yes, sending St. Michaels out would see a Cork side be more competitive with the likes of Rathmore, but on the other side, Kanturk are probably well above the rest of the Munster sides at this level (and probably many more around the country), they eased past the Clare qualifiers the round before by something like 14 points, can only imagine what St. Michael’s would do to a team like that and how it would benefit no one really in the grand scheme of things.
Ultimately, these are bonus games aren’t they? Nice if you win sure, but not the be all and end all if you don’t, not quite meaningless games at the end of an already long year. The standards and gradings across the country vary too much to read anything massive into them.
Look at Ballygiblin, they were in the 6th level of Cork hurling last year and lost the junior All Ireland final by a point, they were tested more in the Avondhu championship than they were in the semi final of the All Ireland and they seem well on course to get back to Croke Park again, should we realistically be sending a stronger team than Ballygiblin into that junior championship when they’ve shown they’re well able for anyone they’ve met? Personally don’t see the point or benefit of it.
