No other choice than what?
The only reports we've ever had, and they're not confirmed, of course, are that the Red Sox offered either 300 or 310, and Mookie came back with 420.
But the fact is that none of us know if there were any other negotiations that may have led Henry and Werner to conclude that it just wasn't happening.
And I think it was you who floated the idea that after negotiations with Mookie stalled, they pivoted to the extensions with Sale and Bogaerts.
