I was just trying to find some quick decline comparisons for Stanton and was looking at McGwire's page.
The steroid era was f***ing bonkers. Of McGwire's last 4 seasons, ages 34-37, his very last 2 were basically half years. He hit 32 and 29 homers in those years, after 70 and 65 the two years prior.
So in the twilight of his career Mark McGwire was hitting dingers at roughly a SIXTY-FIVE (65) HOME RUN PER 650 PLATE APPEARANCE PACE!!!!
