I admire the Board for this. If Everton want to chuck money at it, for their sake it had better work out. I get frustrated by fans just wanting the Board to throw money at it (or assuming we haven't or won't). It was only 2009 that we went into administration.
Depends how much money and to what ends. Running at breakeven or slightly better? Good idea. Running in such a way as to try and turn a hefty profit for a couple years? Just as risky as spending too much.
