This to me seems to be the same argument that originally happened around Crandall. Yes, it's possible he might come good. If we were comparing him against some other Brits, I could accept that. What's being suggested though is that he'll go from a very poor season, even for a Brit, to performing at import level. I just don't get that. Personally I prefer to limit uncertainty.
Similar arguments could be had around Ben Davies. Yes, very high quality for a Brit, but if we want to increase our face off wins, there's an argument to go in another direction.
