BTW, I found that many managers do not use all roster space. They only maintain limited number of players sufficient for their normal squad rotation. In fact, the unused roster place can used to occupy true reserve players who are used in bad injury situations.[/QUOTE]

The reason for this in the higher levels is that Quality seems to win over Quantity, we would rather have a 17 man 6-7*squad with overall Quality of 218.7 than a 22 man squad mixed of 5-6-7* with an overall Quality of 215, it is too costly to maintain a full 22man squad
