No individual is bigger than their concern over a certain view of "the integrity of the game". There is NOBODY who won't get thrown under the bus to "protect the shield" (to borrow a term that the NFL loves to throw around). Players are 100% expendable to protect the brand. You can argue about whether the league has lost perspective on how to handle this particular issue (in my view it's a toxic blend of overreaction mixed with a fair degree of ignorance), but their chief focus is protecting the MLB brand. Pro sports leagues in the US have the money and clout to really take a fresh look at how to build better systems for doping control and adjudication processes, but they simply don't want to get involved. That is so, in my opinion, because if they actually did do anything procedurally to even the playing field they'd take a huge amount of flak about "caving" to the dopers. MLB's chief concern is putting on a convincing enough show that they care about doping control, so as to keep Congress and USADA out of the picture. If you start imposing two-year bans on players for first offenses (as would be the norm under a USADA regime), or if you create a system in which guys can inform on other guys to get leniency for thier own transgressions (as would also be the norm), you would have an unmitigated disaster on your hands as MLB. So they adopt the broad framework of international standards, adopt the "if we say you're guilty, you're guilty" mindset and say the right things publicly to appear "tough on crime". This provides them with political cover and allows them to run their own show. Whoever ends up in the way of that train is collateral damage in the larger battle of MLB retaining its autonomy in this area.
