Yeah, that's where I'm at too. I think there will be punishments for any tack combos that were clearly not formed by a string of league approved items (bullfrog sunscreen and rosin guys won't get shit), such as Bauer's secret Coca-Cola concoction.
I don't think there will be suspensions or bans (more than half of the league would be suspended), but I can see hefty fines for those cases. I actually think the MLB league office purposefully told players they won't get in trouble this year so they can get a wider range of studies on substances done and having the players act like they have been is the best way to accomplish that.
I fully believe the industry belief that the MLB is going to study all of this and come up with a league approved substance that pitchers can use but that doesn't egregiously change their stuff. 1st year teams have had to surrender certain analytics to the league office, so some kind of real-time policing system is coming for guys who try to use something outside of that IMO.
