It doesn't mean that they are not playing. Just means that they have players out of contract that they have not signed for the new season. So it won't show in the team summary screen. I am quite sure he will have a full squad by end of Day 2, coz apparently if you renew contracts on Day 1 you can only renew for 2 years. So he is being smart. Probably signing new players to replace those out of contract. So don't get too peeved. He's active, not a bot. Anyway, if you are low on tokens, buy the 30+ year olds. They will do the job in the short term. As you go along in the season you can pick up the premium players.
