If you think the budget was no factor, why not keep Sale and sign Giolito?
Sale + Giolito has to be either better or the same as just Giolito. That's beyond dispute.
And if they need a second baseman that bad, there are other ways. Grissom was a prospect, no more no less.
I have no idea why you would think "replacing" Sale was necessary. Talk about making ZERO sense. This is starting pitchers we're talking about. You've talked countless times about how a team needs a pile of starting pitchers to get through a season.
"Adding to" Sale - yes, that would have made sense.
