I think its awesome, because it gives me a rough idea of opponents behaviour in how he uses his team. This is very usefull information for a quick-check, because most of the time is quite sufficient just to check ratings and tactic from past 3 games.
I would like to have the opportunity to filter this thing out differently, so more priority will be on starters or more priority could be in played minutes (in the case that this team usually win by big numbers). also could be great if I could switch between shorter and longer period. So 1 full match in the checked week can give me rotation player, while this can be different for past month. Maybe there could be * (star) or something that tells me that this player was injuried during that period.
Im not sure if it isnt too much information, but I would be quite satisfied with 1 thing like that. Problem is that top teams are looking quite similar, especially if they are clever, so I think that it could be more usefull.
