Crap like outlier seasons, photos taken years apart and from altogether different angles, whether "he just looks like a juicer"... none of that is even remotely conclusive. If we don't have drug tests, doping schedules, receipts... some sort of hard, reliable evidence, we have to give them the benefit of the doubt. The burden of proof should be on us if we want to accuse players of juicing. There is no way for them to prove that they didn't.
