Signed no one? They signed a lot of guys last year, they probably gave out more free agent contracts than almost any other team including to MLBTR's #9, #15, #16 and #49 top free agents. They didn't work out, but overall by the time March rolled around people tended to be satisfied with the effort made. But that equation is backwards if you look at how championship teams are made up. Overwhelmingly, teams that win have developed their own, then supplemented. For non-big-pocketed teams this has been the case almost without exception, with the 1997 Marlins being that exception because they did spend like a big-pocketed team. The Twins haven't done the develop their own step yet.
