Logan Webb just got his extension last year... very reasonable deal.
That said, the Giants are in 4th in the West, under .500.... they aren't going anywhere.
His K rates won't wow you, but he consistently takes the ball. Is just 27.
The Giants have a huge investment in their roster over the next 2-3-4 years, Webb is clearly above well above the not-reasonably-available line.
What's the difference between him and Robbie Ray? Maybe nothing, but Ray was a giant salary swap because they liked that cost profile better than the guys they were dumping on the Mariners. They went after Webb and HIcks.and they may be looking at Ray as a thing, but it's at least reasonable they're not. Take the salary (no chance to get out of the guys they traded, now they essentially could) and get something modest back...maybe that's interesting.
I typically like Farhan, but they're another group that seems to accumulate players rather than build a Team.
