Why is nobody talking about the Alabama 2nd runner? He got confused and ran the 1st 100m in lane 6 when he should have been in lane 5. So technically Alabama should have been disqualified.
Why should 'Bama have been dq'd? He ran in a lane outside his own lane so no advantage there and he didn't impede another runner.
No dq.
you aren't allowed to go out of your lane, inside or outside
if you pause it when 43.8 is on the clock you can see him in lane 6 right in front of the texas outgoing runner who is looking back to receive a baton.
