7 players on the injury list is not bad
imo, especially if you are at midpoint of the season. I have 3 of 4 ST out, 1 GK, 2 DC 1 DR, 1 MR all first teamers out at this point 3 of those on 4 month injuries which might see them back for the end of season games, also have some injuries in my reserves an U18 one of them my 5th ST but it's still managable.
You have to prepare for the worst, and also have flexible players, I think it's realistic the way it is, shure it sucks when your 8.12 DC in 15 games goes out for 4 months but see it as an oppertunity for your young guns to step in
