A quarter into the regular season, general managers now have more of a bead on their team and the holes that need to be filled. They can look for trades to see if they can acquire the parts they need, but there is still another way to fill them: free agency.
There are still some notable free agents left that went unsigned during the offseason. If the right offer is sent their way, they can fill their holes with nothing lost but money.
You could argue that all 30 teams have holes to fill somewhere, but I will focus on the nine teams that I think have the most glaring holes.
