As we're now in the midst of the free agency period, plenty of teams are looking fill some holes in the quickest way possible in a world with no trading...free agency. Personally, with 3 pitchers and 6 position players I'm comfortable with on my current team, I was looking to fill 5-6 major holes on my ML team. But much of that help is going to have to come internally or via the waiver wire, because the free agent pool is veeeeerrrry bare. If you're looking for defense, it can be found, but don't expect them to be able to hit. If you're looking for power, it can be found, but don't expect them to hit for average. If you're looking for solid pitching, don't expect any stamina, because you're likely going to have to settle for relievers.
I did a little digging, and based on some of my players and others I picked out at random, many of the better players were initially signed to 3 year contracts. Toby Hutchinson, "The Gift", is one example of this. So I expect season 4 to be more like a typical free agent pool most are used to in HBD. BUT, what I've also found, is that because of the lack of teams trading to become lopsided to take them to one extreme or the other (win now or win later), players that I wouldn't have normally played in the ML are finding a legitimate spot.
So don't feel too discouraged if you went into free agency hoping to solve all your problems, only to be left out in the cold with no answers for many of your spots. Find your best option, plug 'em in, and hope for the best. Just remember that there are no excuses for failing to meet 55 wins. :)
