I am fully aware of that and I have said many times that I do not want him playing first base. I think he has the athleticism for it, but I don't think he has the concentration for it.
That said, I don't think the Sox should just give him away, just to have him off the team, especially now in light of the fact that Ortiz is retiring after this season. My hope is that Hanley can at least be serviceable at 1B this season. I think he can be used in the DH role once or twice a week, and he can be replaced with a defensive sub late in games that we're leading.
If worse comes to worse and he ends up being a real liability at 1B, then Shaw can take over everyday 1B duties. If that's the case, perhaps Hanley will have recouped his value offensively and some team will need a DH at the deadline. If he's not traded, at least he will have a position in 2017.
