Right, there were some really fast guys on the pro side in that meet, and it's not like it was an Olympic meet. As you know a lot of the best sprinters don't even bother with indoor 60s. As I recall TCU had a good track team back then and a couple of their guys were running... I'm pretty sure one of the guys even played football for TCU. I could probably figure out who it was if I tried... This was probably 1982 to 84, somewhere in there, and I'm pretty sure Wacker was TCU's coach.
TCU is the only school out there can can fill 8 lanes with sub10.00 sprinters among the alumni.

Phil Epps the footballer a 10.2ish can't make the final.
Nobody can run a 100m all out so ya train for the different phases, the start, accelleration, sustaining topend and decellerating. Those capable of maintaining their topend longer meaning less decellerating have the advantage. this is.....speed endurance....and that takes training.
Usain Bolt took so long to hit his topend he spent less time decellerating.
As far as Roscoe Tatum goes...
