That's the thing, I don't think he's even peaked, I think this is just his natural beginning. Just like the decent freshmen end their first year with a 2:0x, he'all end his with a 1:4x. He's just that good. He could easily end up being a 1:43-1:44 guy by his senior year, and if he really is maxed, he could easily just improve his 1500/Mile because he's not done there neither. Michael Granville was a whole different case, he was over trained from a young age to get his times, his 1:46 was probably a 95-105% effort, meaning little to no room for improvement. I don't know much about George Kersh, but I know he ran close to the same as MG and still went on to have a professional career. Same for Donavan Brazier, about a second slower and still went on to improve; this kid is in the same league as them.
