He never said about getting the back row as close as possible. He said as steep as possible. (Edit: Going by the printed edited version anyway, 2nd edit he did say as close as poss haha!)
Steepness of that seat without meaning making that seat as close as possible means we could be having that seat miles away from the pitch, or very tight legroom, it means you cannot make that stadium bigger, it means no standing, and no standing drastically cuts the atmosphere. It means they've missed the point on what people are trying to ask for.
If people misjudge what they ask the club for they will be in for a shock when they actually settle into the new stadium.
