Let's get the obvious ones out of the way: Strong, Swagwood, Beaty for sure. Hell, Strong might just be the strongest coach in the country, pardon the pun.
Gundy and Horsewomen probably could as well.
Rhoads? I really don't know. Could Stoops? I'm guessing not.
Certified weaklings: Snyder. Patterson. Briles is probably too old to crank out 20 good ones.
So here is my list of coaches who could do the most pushups in a row:
1. Strong (45 shups)
2. Ryan Swagosling (40 shups)
3. Beaty (34 shups)
5 (tie). Gundy (21 shups)
5 (tie). Holgerson (20 shups)
6. Rhoads (17 shups)
7. Stoops (14 shups)
8. Patterson (11 shups)
9. Briles (8 shups)
10. Snyder (0 shups)
