I don't think we ever got that close with Baldock, not even sure we agreed the fee with Mk Dons.
The only player that I can remember who agreed terms, had a medical etc...then ran, was John Halls back in the summer of 2005. There was an article on the OS, pics of him at the training ground etc - then a day or so later he turns up at Reading.
Don't think we missed much there seeing as he's turned into a pretty average L2 player.
