The whole point of finding a new 1B is so there is an actual 1B playing 1B this year, and not a bunch of 2B, SS, 3B, etc. attempting to play there. There is absolutely no chance that Weeks will be tried at 1B. He'd be horrible there defensively just like everyone else that was trotted out there last year. There's a reason 5' 10" guys don't play 1B, not that that's even one of the main reasons he'd be bad there.
