I agree with this, Mason was in good form when McCallum took his place. They obviously thought Sam was ready for the first team to play him but i also feel that he was in the shop window for obvious reasons. The clubs situation makes this a necessary evil.
I'm assuming this is the full of shit chant you're talking about, there were some twats in block 34 who tried to get it going but thankfully it never caught hold past a few on the left of 33, i just shook my head at the bell ends.
