LOL no! 5'9" and 198 would be considered quite skinny for someone in a strength sport. Some weighing 230 wouldn't be uncommon at that height. You didn't start seeing "fat" people until you get up to the 250-270 range. One big difference between the tested and untested competitions was with those big guys. Untested competitions would have guys who were 275 but still quite lean. Tested would not.

I doubt any of these guys are over 5'9". and they are competing at ~ 205 which means their day-to-day weight is likely 215 or 220. Drug use is possible, but this is a tested competition.
My 5'9" friend who was competing at roughly 220 (and thus typically walking around at 230) definitely wasn't taking any drugs.
Me at 5'8" and ~185 walking around weight: note how I'm just about the skinniest guy there. People would joke about how "lanky" I was. I certainly wasn't being accused of taking drugs.

People tend to gravitate to what they are good at. Thick, big boned, mesomorphs, the kind of people you don't see doing endurance sports like cycling, can easily be 5'9" and 200 without being fat.
