I can't figure out how to change the lineup for my team. I'd like to be able to do this before and during a game. Seems this should be easy but it has me stumped. Thanks

The tutorial part 3 at this URL shows how to rearrange lineups:

During a game, you can use Misc->Show Starting Lineup, then rearrange any way you like.

Do not use this method for substitutions as this is only for changing the Starting Lineup. Substitutions are done by tapping on the players in the field that you want to sub for. The video also covers that.
