February is here, so it's hard to believe that that many free agents are home sitting on offers, waiting for bidding to increase. Then again, with so many major leaguers still available, the Red Sox could easily add another starter, reliever, second sacker and/or centerfielder.
The costs would appear minimal vs. the depth still needed for max improvement... because, although the roster is better, we all know -- barring many, many what-ifs -- it's probably not good enough yet for us to watch a winner, much less a contender.
