Very good piece. That kind of analysis from Pat Nevin always contrasts sharply with Shearer etc mugging to camera before telling us what we can already see for ourselves. Less relevantly, he's got superb taste in music as well (Nevin not Shearer).
A quick flick through http://www.footballgroundguide.com/ suggests that most of the pitches in the Championship are pretty close in size, with the exception of Millwall which is a fair bit smaller.
