It sounds like he was behind someone else? What teams were ahead of him? Any idea of the splits? Here is what I found on the A&M site.

Following an opening 1,200m leg of 2:56.07 by Donavan Brazier, Robert Grant fell flat on the track after the exchange of the baton in a collision with another team. Grant still managed a 50.38 split over 400m. Hector Hernandez then made up the ground to the leaders with a 1:47.59 carry over 800m, which was the fastest split among the nine teams in the race.
Cameron Villarreal covered the anchor leg of 1,600m in 4:01.59 to place third. Oregon's Edward Cheserek split 3:55.70 on the anchor for the win while Oklahoma State's Chad Noelle, the 2015 NCAA 1500 champ, split 4:02.03 as runner-up.
"For Donavan to run that fast on the first leg is very good," said Henry. "Plus he learned some race lessons tonight. Then we got knocked down and Robert was able to jump up and do a good job with his leg. Hector ran a great 800 in splitting 1:47 and it was a tremendous effort. Cameron closed strong with a 4:01 anchor."
