Why would they?So… this team is going to expand their payroll by 70mil this season and beyond now?
First of all, we don't know tha the Jays were going to go as high as $700M over 10 years.
Most of the $700M in the Dodgers deal won't be paid to Ohtani until after the 10 year deal has run its course. Since the deferral was apparently Ohtani's idea, it is probably safe to assume that a Jays deal would be structured similarly and thus, the actual hit to their payroll would have been far less than $70M.
Finally, the return on investment for Ohtani is much higher. Spending $700M on Ohtani would bring n much more money for the Jays and Rogers than spending ppl that same amount on other players.
