that stops everything, lol.

don't use it unless you want to control every team.

think free agency or related rules are in "options" maybe "rules" of the league.

you could even make service time so difficult to obtain, that they never gain any years toward FA.

think you have multiple ways to achive the goal, and it depends on other details which is best. if you can't turn off FA, you'll have to go more roundabout like affecting service time.

oh, just in case that doesn't do what you need: you could make a "human gm" for each team and delegate all functions except sing/release.

either way, you may need to micro manage these teams if they cannot sign FA.

with no minors, you need reserve roster instead? think that will reduce the opportunity to sign/releas in general
