how the waivers work

I notice that teams are dropping players without picking one up before the waiver period has expired. Does that free up money for the waiver claims? Is that the purpose? I assume I can't drop a catcher unless I have three.
Also can I make contingent claims? Add a catcher, drop an expensive catcher. Next, add a catcher, drop the same expensive catcher.

This is true.

You need 2 catchers on your squad at all times, so yes.

Yes. There is no limit on the number of waiver claims you can make.

The game rules can be found under Info/Help on any of your teams pages. Here are the Preseason FAQ's. Many questions about waivers are answered there.
