I have 12 teams, some of them at LV1 (with the relative grass lv quality).
the frequency of injuries is about the same with my LV33 team with full stadium and usually the abnormal formation (or very bad morale affect it and not the grass).
If I 'll remember, I 'll make a post about the injuries of two teams in the first round.
About morale, doesn't matter.
Excellent, very good, good is ok.
I don't bother to keep full morale in my players.
I leave it more to use it as an indicator to see which player maybe is out of form.
When they go to bad, then I give a double blue to fill the bar.
I would gladly exchange my blue packs with some greens

That's the team right now.
One draw and the rest are victories.
