Each MLB team has experienced some form of offseason regret in terms of free-agency signings or trades that didn't quite pan out as expected.
There is no exact science or perfect formula used to determine the perfect transaction—way too many variables are in play. A free agent could be looked upon as the perfect solution for a particular team's need, and the decision is then made to acquire that free agent to fill that need.
Seems easy, right?
Well, one only has to look at Chone Figgins and Jason Bay to see that it's never that easy.
At times, a regret can include a transaction that wasn't carried out. Not pulling the string on a particular trade or not making an offer to a free agent can, at times, be an MLB team's biggest regret.
In looking at the current offseason, each team has already engaged in various transactions designed to bolster its roster for the 2013 season and beyond.
Here are the regrets each MLB team has so far this offseason.
