I've been around these forums long enough that I'm used to it happening after 7 minutes, let alone 7 months...
In all seriousness, I think it's fine to question their ability after 7 months as long as you're keeping an open mind and aren't entrenching yourself in a position. It's reasonable to suggest there's a chance Widdell could be more of an Eom than a Vipotnik, although as I've already said, I don't think we can make any definitive judgements yet.
As for NJ's post, I'd say there's posts that argue the opposite to tardylum (which is of course fine), then a quick move to mocking the poster for daring to express a mildly negative opinion, Flash being the worst culprit in this thread.
The likes of Cullen, Key, Ronald are given a far harder time by many more posters and while plenty of us defend them, I don't see the outright hostility shown to those posts as opposed to any claiming the more recent transfer activity is anything less than perfection.
