depending on individual player settings, 65 - 70% is still quite high specially if your team isn't to strong yet. i have a 60* team with many skills maxed for my level but i only play at 70% player rhythm and 55% rhythm at team strategy settings. a low hands off setting also prevents injuries and high or maxed 'tougness skill' also helps a lot. most of my players hav maxed or high toughness skill, that with my carefully tuned strategies have made that i haven't had any injuries for quite a few seasons already
