It would be cool to open up the budgets a little more. If you limit international free-agent spending to $5M, combine the scouting budgets (HS, COLL, IFA) into one and boost the max to $30M to cover all three, and streamline the coach hiring (one hitting, pitching and bench coach for all levels, like the fielding instructor), it would open it up to more free-agent battles in the preseason.
Also, something needs to be done about minor-league free agents asking for $3M when they haven't played in the majors.
