I think it absolutely can be both. It was the transfer equivalent of a hit and hope. For me, it was an unnecessary level of risk in that particular gamble, and while it had no transfer fee attached, the wages we've paid (and are still paying a decent chunk of) aren't nothing. Funny how people will berate the Rondon signing - correctly, tbf - but not this one (not saying that's you - CBA vaulting you on that).
You're right, though. On the whole our approach has changed and we've cleared out most of the crap. I don't want to tempt fate but I don't see us taking on any more hit and hope style transfers in future!
