Ohio State doesn't mess around with 2nd and 3rd team All Americans - you don't get a tree in the Buckeye Grove for that.
So, let's compare First Team All Americans from 2015 to 2019:
tOSU: 8 first team + 4 consensus first team + 5 unanimous first team = 17 total
scUM: 2 first team + 4 consensus first team + 1 unanimous first team = 7 total
Note: Six of Harbaugh's seven All Americans came in his first three seasons (2015, 2016, 2017), and they were all Brady Hoke's players.
Harbaugh had one All American in 2018 (Devin Bush, his own signee).
Harbaugh had zero All Americans in 2019.
Harbaugh has zero 2020 preseason All Americans (either first or second team).
Just wait until Harbaugh gets his own talent in Ann Arbor .... LOL
