Good enough? 
As a HS Sr Sherman 6th in the LJ, 4th in the HH and 1st in the TJ in the California State Meet

Actually no.
You don't quite need elite sprinter speed to win any of those HS events.   It helps most in HH, but good form, especially in HS, will get you far.
Generally those that run HH are doing it because they aren't fast enough to run the 100 or 200.   No doubt he was/is faster than most HS sprinters, but there are some that are faster.   

Most days the WRs in the NFL are not really able to utilize that extreme top end speed often, so Sherman's understanding of the formation and the routes is enough.   In most games the best DBs are faster than the WRs, and that just isn't true in Sherman's case.   That's OK.  More to being a good DB than 40 times.

The Chiefs WRs are exceptionally fast and Mahomes' passing abilities may allow them to get a long TD or two on Sherman.  No doubt the Chiefs' WR beat Sherman in the 40, but can they get into plays that give them enough time to exploit that difference?   Will the WRs get the TDs or will Sherman get the INTs?   It will be fun to see.
