As for CF vs LF. I think to upgrade 150 OPS points from Ludwick, you'll need a guy in the .875 range. That's expensive and hard to acquire. I think the same upgrade from Hamilton would be a .725 OPS guy (yep, I think Billy will struggle to OPS .600 if you're doing the math).. Those have been out there and wouldn't have cost a ton in talent or money to add it. If Hamilton gets it together, that type of player wouldn't be a waste of budget or talent sitting as a reserve, or worst case, get's dealt again to recoup the talent expended to acquire him.
