10.9 for males is “fast” but not elite fast. For comparison sake I ran a 10.7 and didn’t even run track.
Not calling bullshit, but I was a very good track athlete in HS as my secondary sport and a FAT 10.7 is absolutely "elite" (i.e. good enough to have your running in state finals in most states) for a HS boy.
In Virginia last year we only had one athlete that ran in the 10.5s. Everyone else's PR was in the 10.6s or worse.
If you were running 10.7 without track training, spikes, blocks, etc. then you
should have been running track because you could've run at most colleges.
But hey I don't know your story, maybe you dominated in some other sport and it didn't matter. Just saying a 10.7 is VERY good.
And for a tall WR, I think anything sub 11 means they have potential to have good-to-great football speed. CJ Prosise -- for example -- was an explosive football player and ran a 11.00 100m dash PR.
