I can understand if Harkin had played poorly, but he's been excellent in his outings. A few jitters initially which is understandable in your debut season but from there he's been great. Really hard to understand.
The Lions & the Canes seem to have this same problem where they'll continue to pick complete journeyman players for year on year, even if a young guy is banging the door down. Same situation with Prinsep and Blackwell.
