That's 2 sub 1:44 guys in the NCAA this year
Brazier at 1:43.55 and McBride at 1:43.95
McBride followed the rabbit for 550m (a few meters back), but acted as a great second rabbit for Bosse (the eventual winner) who ran a SB time of 1:43.88.
The NCAA was incredible at 800m this year. Feel sorry for the number 3 guy...
Brazier's season is finished, but who knows, McBride could go faster still. At a very minimum, he was running pretty much in the centre of lane 1 in the turns rather than hugging the rail (like Bosse did). That's a few hundreds right there.
