That and the 12 year commitment if all of those things snowball.
Also, worth pointing out AAV math (for luxury tax purposes) for pre-arb extensions and how that has changed for traded players in the new CBA. Pre-arb extensions typically have the same escalation as normal contracts where money increases until year 6 and maxes out after that. This drives the AAV way down for the back end of those contracts. Now teams that acquire players get the AAV from the time of the trade to the end of the deal.
Tatis's AAV number right now is about $24.3M.
If he is traded this offseason, it is about $27.8M.
Also, reading between the lines on how Harris has talked about a development culture, I have a feeling soft factors like work ethic will be emphasized a lot by this front office (and could see that rubbing people here the wrong way).
