Yes!!! So if they named 80 people does that mean they got most of them? No!!! They haven't checked all dealers, just a few. Then they found the players from a few dealers.
In a sport where testing is not very strong and there are $100 million dollar contracts available, the need for steroids is high for ALL players to level the playing field.
Old players use them to stay at a competitive level. Average players use to get to that upper contract level, poor players use to stay in the majors.
The best example would be Adrian Beltre. He was an average player but then he exploded one season and hit 48 homeruns (twice more than his past career high) and hit .332. Despite his history of being average, he got a huge contract to play in Seattle.
What about those who come from poor countries? If they don't get the huge contract, their family doesn't live so well back home!
Would you really be surprised if 90% of players used before? Back then without adequate testing, what prevents a player from using?
Use your brain and REALITY!
