There isn't a team in baseball that doesn't head into the offseason looking to improve, but only a few are typically able to do so in impressive fashion. After all, there's only so much talent available, and the price to acquire that talent is often counterproductive to what a team is trying to do.
Since the Hot Stove League began in November, multiple teams have been able to make impressive improvements to their rosters. But how do we quantify impressive? It's highly subjective, as what impresses me may not impress you, and what impresses you may not impress your best friend.
To do so, we'll look at a number of factors, primarily the statistical improvement over what a team had at the position a year ago compared with the numbers of their newly acquired talent, as well as what it cost a team to acquire those players.
Teams that were able to improve multiple positions will land higher on the list than those that filled only one hole because, well, it's much harder to acquire multiple pieces than it is to land just one.
Lets take a look at the 10 teams that have impressed us the most so far this winter.
