I believe the reality is that Brady was happy with the financial situation he left behind. However this was based on larger attendances. Apparently Lynn need approx 900 fans to break even based on their current commitments, so i guess anything less is what's causing Buster to suggest they are over budget.
Brady quitting for personal reasons couldn't be helped but unfortunately one thing he has to take responsibility for is that he built an extremely poor team at the start of the season and now Lynn are paying the price for it.
When they come back to tapes, i expect there will be at least one rider change which will reduce the cost of the team.
