1. Boston Red Sox
If there's any team that has missed the boat on signing certain free agents in the American League, the Boston Red Sox would be that team.
Aside from signing Lucas Giolito, the Red Sox have sat idly for much of the offseason, letting several free agents sign elsewhere instead of making a move to improve the roster.
The Red Sox have several holes to fill on the offensive side, especially after losing Justin Turner to the Toronto Blue Jays. Adam Duvall may also leave in free agency.
They did add Tyler O'Neill and Vaughn Grissom in trades this winter, but that won't be enough to make up for the losses of Turner and potentially Duvall.
Profar could have filled the void quite nicely if the Red Sox had taken a chance on him. They have holes in the outfield, at the designated hitter spot, and at second base, and it is unclear if their internal options or new additions will ultimately be enough for them to make the necessary offensive improvements to return to contention in a very competitive AL East.
For now, the Red Sox remain dormant, with no sign of any major additions coming soon.
