Doesn't that leave the system open to even more abuse though? If you're only tested X amount of times per season and you happen to hit a handful of tests early like Gomez, the chances of your name coming up again are slim, which makes it easier to get use illegal substances. The current system certainly isn't perfect, but since everybody reenters the "lottery," before each test, they all have the same chance of being tested on the same date, which at the very least eliminates the possibility that some will have an advantage over others in terms of a window to use. I agree, there likely are a good number of players who aren't caught simply by dumb luck, but apart from weekly, or in some cases almost daily testing of all players I'm not sure what more MLB can do to catch users. It's hands down one of, if not the most stringent testing programs in all of sports. There are always going to some who slip through the cracks.
