Yeah maybe just north of 2000. Whilst what you say about the big/local teams coming, you've also got to consider the poorly followed teams and ones visiting on a midweek night - Millwall, Preston, Portsmouth etc. Then Swansea, Watford, QPR, Blackburn etc. They'll most likely even the big followings out.
Anyway besides the point. I don't think we'll average as high at 29k.
