What bandwagon did you jump onto? How in the name of something holy or ungainly is Baines almost as good as they come defensively for a fullback? If you had said for a winger, I would still give you Valencia as a better alternative, on the top of my head. Every stats you can find will show you that Baines is below average in the PL defensively. He's terrific going forwards, but defensively he's a couple of levels below Evra and a few more so below Rafael. He struggles for pace every so often, he lacks strength to outmuscle the stronger wingers and he isn't particularly good in the air. Evra makes more clearances, more blocks and wins a ton more headers than Baines does. He is consistent, but defensively he will certainly be no upgrade at all. In fact, if we study our alternatives, Evra, Büttner, Fabio and then Baines, I think Fabio may prove out to be the best defensively with Evra second and Baines third. Going forward you need to just flip it. It all depends on what you want, but performing brilliantly for Everton is not the same as being able to do that at United, and being below average at defending doesn't bode well, imo. (That's not just talking stats, that's also taken from every time I've watched him play - he isn't impressive at defending)
