Insufficient evidence to show anything other than bad luck or bad karma.
Be interesting to see a link to the whole team to see if entire roster is cursed or just these few.
Might be interesting as well to go over some past teams with these players and see if error totals are consistently higher than expected. Oh wait, we can't get to old teams.
Guess we will have to hope Nev or someone with a million active teams can chime in with numbers from current teams to provide meaningful sample size.
