Having considered a few specific players, it may be worthwhile to take a step back and look at the bigger picture. Listing the skills or abilities the team wants to add is easy: shooting, quality passing, perimeter defense, and shot creation for the individual and teammates. Y’know, almost every useful skill on a basketball court.
Instead, let’s look at this from the other direction: which positions do the Magic need to upgrade if they want to get better? This isn’t necessarily about the kinds of players the Magic want to add (e.g. an “attacking point guard” versus a “floor general”), just about where the team is getting the least production right now.
