3. Tony Mandarich (Michigan State)
If the recent scandals around steroids and performance enhancing drugs over the past couple of decades has taught us anything, it’s that America hates cheaters. So naturally, Tony Mandarich would be on this list. After finishing a highly decorated career at Michigan State, scouts and media began referring to Mandarich as the greatest offensive lineman prospect in the history of the NFL Draft. After all, just think about a human being who weighed 330lbs, ran the 40 yard dash in 4.65 seconds, did a standing long jump of 10′ 3″, leaped vertically 30″ and did 39 repetitions of the 225lb bench press. As we later found out, it was all too good to be true. Mandarich admitted to using steroids throughout his career at Michigan State, and even faking drug tests to ensure he could continue to play.
