In his NCAA semi he had 41.5 strides.
Compare that to his 200m compatriots Boling at 45.5 and Laird at 47.5
Also compare it to the other super-long-striders in the 200, Lemaitre and Bolt.
Lemaitre also at 41.5 in his 9.92, Bolt at 41. Bolt had less than Lemaitre because he had a more powerful start, and didn't waste kiddie steps.
Spearmon had almost 44 in his 9.96
In any event, Fahnbulleh is in good company. I haven't counted his 200m strides, but geez.
In thinking about what he might do in the near future, I think Lemaitre is a good comparison--less of a start, monster stride, amazing finish.
BUT CL went 6.55 in the 60, whereas JF has gone only 6.73. That is an enormous difference. JF is really missing not only blocks, but early acceleration. That's a big deal, there is that 0.20 he his currently behind CL in the 200.
Do I think he can get there? YES. He lacks that acceleration because his body is not in the position to generate it. Weak as CL was, he did know how to get something out of his body in that phase--6.55 is not chopped liver. Even if JF doesn't get block explosiveness soon, he might be able to put his body into a better acceleration attitude early--I mean, even his SET position is terrible--legs at the wrong angle, curled-over lower back, terribly bunched, no possibility of exerting force along the beneficial line. He then bends a lot at the waist on early acceleration.
This guy could IMO go 19.8 at any time, with no extra effort, if he just fixed his blocks! (I'm sure that his coaches haven't thought of this :) )
He is still loping down the track. Amazing to watch, because he could bust one out at any time.
