Things happen. Or sometimes, nothing happens and kids then get frustrated because they can’t figure out what is going on. I hope he recovers because he has great talent.
It has happened many times before though. Do you remember Josh Evans? He was 4th in the Dream Mile in 2014 behind only Fisher, Maton, and Haney hitting a full mile in 4:04. This was in the olden days (before 2015) when the best high school runners didn’t break 4. Probably even more impressive was his state meet performance where he won 4 events going 1:50, 4:06, 9:00, and split 1:49. Evans went to distance power house Iowa State for 2 years but transferred after 2 years to Colorado Mines and now hit a college best of 4:10. Sounds much like Slagowski.
