That's strange. One player plays the whole match for the team.
I got maybe a solution for you guys.
Wouldn't it be better for example like one player will bowl ten overs and the next player bowls ten overs, etc. So five players will bowl the whole match. (with just passing on the save file to the next person).
If the opposite side is bowled for 40 overs or so (4 players only played then), then the rest of the remaining players who didn't bowl (7 players) should divide the 50 overs by 7, so each player will play 7 overs. And after 7 overs, just pass on the save file to the next player.
I mean with that each player who is in a team will at least have a chance to play the match.
Players who didn't play the match will start as first player to bowl or bat in the match.
Just a suggestion. But I don't know how you guys play in this match. If only one person plays for a whole team, that isn't good.
