So, we have an offer of 5/115 on the table, if another team says "Hey, I can afford that!" and makes the same offer, Springer isn't going to just take the new offer, his agent is going to come back to the Jays and say "we've got another 5/115 offer on the table, can you beat that?"
And the Jays already know their min/max value on Springer, and will counter offer at that point.
There's literally zero advantage to the Jays tossing around $150M at this point, even if they have $150M to spend.
