There's probably never been a bigger meathead than Tony Mandarich.
At 6'6" and 330lbs with 11% body fat, Mandarich absolutely crushed his NFL combine workout and got himself selected in the top 5 in the 1989 NFL draft- ahead of 1st ballot Hall of Famers Emmitt Smith & Deion Sanders.
On the field you would never know it, but on paper Mandarich was a monster who was faster than one of them and stronger than both of them.
Mandarich ran an official 4.65-second 40 yard dash time (which was faster than Jerry Rice and Emmitt Smith),
- benched 225lbs x 39 (his max was 545lbs)
- had a 30” vertical leap
-broad jumped over 10'3"
If you don't know American football, those are insane numbers. Even today's best offensive tackles at that height and weight, like Ryan Hayes (6'6 298lbs) ran 5.18, & he although he hit 30", but didn't even attempt the bench. On the other end, Agree Vorhees stands 6'6" 310lbs, benched 225lbs 38x & had a vert of 29", but he's slow.
Comparing him against the WSM guys of that era, the 1989 WSM winner was 6'3" 330lb Jamie Reeves, who was much fatter and slower than Mandarich, but slightly stronger- he benched 601. Mandarich was about the same size & strength as Jon Pall, though, and if he'd gone into strongman they'd have had some titanic battles, with or without Kaz in the mix.
Rather than trying his hand at the mostly unpaid TV game show sport of WSM, Mandarich treated his body like a penny stock- he pumped up for the combine with the knowledge he'd bust once the drug testing in the NFL got him off the gear. Making matters worse, Mandarich stopped lifting twice a day, stopped eating 7 meals a day (totaling 12-15k calories), & dropped 40lbs, so he lost a ton of strength, and fizzled out as arguably the biggest draft bust of all time.
