Convictions aren't necessary to understand what Sosa and McGwire were doing during their careers. Just because there is no hard evidence doesn't mean they're any less guilty. First hand sightings of injections, along with evidence that both were on amphetamines, can lead to more than speculation that both were on PEDs while active players. Add to evidence of Sosa's weight lost and McGwire's inability to admit to anything in front of Congress results in both being highly likely to be involved with steroids.
Now with Ortiz we have an overweight slugger who resembles a fast food abuser, compared to a steroid junkie. Realize that Ortiz has never be accused, never had a significant weight loss or gain in his career, and asides from a breakout season, has no evidence of every taking PEDs. Steroids taken whether while working out or not would lead to a weight increase, or most likely a muscle increase. There are other results but the muscle gaining is ideal one. Can you honestly sit and argue that Ortiz has gained muscle/lost weight in a dramatic fashion?
Seriously just take of the middle school girl panties and man up. There's no sense in acting like a punk, kid.
