I'm a bit surprised that everyone just assumes Sanchez is going to be a back-end pen arm. He looked good in 2014, but there's a long history of control issues there and he doesn't miss bats.
Weeks is not a replacement-level player. Especially if used in a platoon with, say, Kawasaki. And none of Goins, Kawasaki, Izturis, and Santiago are going to easily do anything, let alone average play at 2B in the majors.
The team doesn't even have a 2B. Weeks would slot in perfectly against LHP, and you'd think that would be more attractive than maybe DHing against lefties in Seattle (Cruz will get the lion's share of those opportunities), especially given the friendly home park here.
Damn, the Mariners signed Rickie Weeks for $2 million + 2 in potential bonuses. You have to think he would have accepted the same here with 2B wide open. Would have been a perfect signing.
