If it came to a head-to-head race, Rupp would do what it took to win.
If this is true, why couldn't do this when the winner ran 2:08 in the 2016 Olympics, or when the winner ran 2:09:30 in 2017 Boston?
Which means sitting on Hall till the end and out kicking him. Rupp would not lead a step until the final half mile and then he would blow him away.
With all due respect, this is how high school coaches talk. Distance running doesn't work this way. Go look at the times of the runners that Hall and Rupp actually beat in a race. Has Rupp ever beat a 2:06:30 guy?
