For example, when I go to Team Manager/Roster and look at the players, there are many without player numbers. Also, this list is not comprehensive (it is less than my player list), but does include all the players from yesterday's game (even though I had player numbers for all of yesterday's players). However, when I look at the stats from yesterday's game, all the players do have #'s. Should the #'s be showing in the team roster?
One problem I had yesterday was adding players. I needed to sub a player that wasn't showing up in my list of players in the sub function, even though they were on the roster (in Game Manager). How does that happen? How do I fix it? I somehow did, but I fell majorly behind in scoring, and I'm not sure what I even did!
Should I keep all my players on my roster, regardless of whether they are on the roster for that particular game? In other words, Team Roster = Players List? Does the roster change with every game, but the current state of it will always reflect the current game (or last game scored)? Does these questions even make sense??

I used Turbostats for years and years. I'm excited about iScore and iScorecast. I would have loved it over the last 15 years of sons playing bb, but I need to get over this learning curve!
Thank you in advance for your help and comments.
