Yes in the past I have been frustated with guys falling short like Shirvo, Macro and Nagel to name just a few. It happens. Even with black sprinters many peak early and never come close to those times again. One of our biggest problems other than the psychological problem is basically just a lack of enough elite sprinters competing.If we had a huge interest in athletics within the white community like there is in the black community you would see more sprinters at the top of the bell curve. Too many of our guys play a multitude of other sports and most never even run track. Teeters is just one of countless examples.
I do believe John Teeters can go sub 10. He ran around 3 or 4 times in the 10.1 range this year both with and without wind. He just got nervous at the ncaa champs and tied up bad. The kid will learn from that. Just like Prandini on the womens side, he is too good to fail. I love Devon Allen. You don't run a 13.16 by luck at the highest level of competition in your freshman year unless your gentically gifted.
Hari and Gemeli have not peaked, Gemeli just ran a 10.07 from lane 8 a few weeks ago. He will be a sub 10/sub 20 guy for sure. Kristoffer Hari is only 16/17 so it will be a few years still. He already ran a 10.47 this year wind legal but he has only run twice so far this summer. Expect some 10'3's from him as we get into July and August. There are so many young guys from around the globe. I will have to make a new list of young sprinters to watch. Thomas Sommers and Ryan Gorman are just a few off the top of my head.
The bottom line is to just stay patient my friend. The times will come and once several break the once magical barrier you will see many
more waves in the future. Lemaitre will always be remembered as the first. It still kills me how he has been trained for the last 4 years or so.
He is capable of so much faster times but he like Guliyev has not had the proper guidance at all times. Both of these guys are incredible and they should running with the best in the world all the time. The fact that both have done what they have with neither having much of a drive phase is amazing. Always the last out of the blocks but still able to put up eye popping times. Incedible if you ask me.
