I think that's key. Sir Alex has talked him up a few times, and he's put his faith in him to prove he's good enough to play for us, but people don't care. They always have to form a concrete opinion before he's even given a proper chance and before he's anywhere near showing what he can do at his best.
I thought that it was interesting to read that people saw Fletcher as a playmaker or a similar player to Carrick 4 years ago, it shows how little we'd actually seen of Fletcher's natural (or most effective?) game and his best qualities. The same thing's happening with Gibson with people deciding he's only good for his shots, pinning him down to a set role and skillset (probably before Sir Alex and Gibson himself have even worked out where he's best played yet!). You have Trappattoni and Meulensteen highlighting his passing as one of his strengths, yet you've got hoards of people saying he can't pass.
I'm not saying that because Sir Alex has shown his faith in him he'll make it, not at all, but he's obviously saw something in Gibson that tells him he could make it at the club. So it's worth having a bit of patience to see exactly what it is he sees in him instead of writing him off just because it's not immediately apparent. He's started just 26 games for us, 10 in the league.
Why are people so desperate to be conclusive? What's wrong with just withholding judgement for a while?
The transformation of Fletcher is an interesting one, and I think there's a fair bit to say with regards to it. I doubt that, after seeing him in his younger days, that this is the 'natural' game of Fletcher (it may well be his most suited; however, he seems to be trying to change it), though it's very difficult to talk about what natural means in this context seeing as though it seems to indicate some sort of pre-programmed style of footballer that is innate to him.
Fletcher's transformation as a footballer occcurred in accordance with the stick he got from fans. I think that, at some level, players over here that lose their confidence in expressing their ability then shape their game to at least appease the fans by putting in a hell of a lot of hard work. Park has been through a phase of this, Tevez had this for most of his United career, and Forlan was a classic example of this. When Tevez and Forlan moved on, their was no such limitation on their expresion, nor was the main focus on the commitment and work-rate that fans at least expected. They became the main man, and regained their confidence in their expression.
It's an anxious reaction basically, just as the whole "if things aren't going right, keep the simple things and do them well" lark is. It is the very reason for the way that Fletcher has developed. Perhaps Gibson's expression of his ability has been limited in such a fashion, though I think it's fair to say that Fletcher showed a lot more in the past, which is why it's a difficult comparison to draw. Fletcher altered his game to the extent that the emphasis on technical ability (which he does have and did demonstrate) was lessened, yet Gibson hasn't shown the ability that Fletcher did despite showing sporadically that he can, say, crack a 40 yard pass cross-field, and twat the ball into the net from 25 yards.
We'll see what happens, though I can sometimes understand the fans' frustrations. It's not as if he's starting every week and causing us to drop all sorts of points, but we do look a lot more apathetic (perhaps a co-incidence) when he's on the pitch.
