Well, the times he's posted thus far speak for themselves. He'll get stronger in the coming years and I expect a huge drop in his 100M time when he matures around 20/21, as we saw from Bolt, Seville, Blake....not saying he'll break Bolt's WR's but his trajectory indicates he's headed in that general direction.
Wonder if he could be a 200/400 world beater like M Johnson.
he's at the age right now where he can choose to be a 100/200 or 200/400 guy. bolt had to make the same choice as he was a phenomenal 400 runner early on.
i say he goes 100/200 because: 1. that's where the most money is at 2. knighton is only 18 (bd jan 29 2004) and likely won't hit peak bone density until ~24, which means he is going to get stronger and heavier 3. he has not fully matured from the perspective of coordination
wouldn't be surprising to see him rip a 9.75 this season with a legal tailwind.
for reference, Bolt didn't go sub-10 until 3 months before his 22nd birthday. he did however go 45.35 as a 16 yr old...good god.
