I have been to every one of the outdoor incarnations of this good meet, and each year I see Division I head coaches from around the country there, looking at their incoming talent and/or scouting others. That includes Oregon (every year), Princeton, Miami, Oklahoma, and more. The coaches won't be able attend in 2018, because they'll be in Eugene that day, 296 road miles south.
I think Brooks has made an error in judgment with this date selection, and I hope they can fix it. I for one won't be at the Brooks PR meet this year.
