Afflalo leads the Magic in points and has a TS% of .542 vs .572 for his career. 16.9 pts/36 vs 13.4 for his career. Mayo has a TS% of .591 this year vs .537 for his career. Scoring 18.1 pts/36 vs 16.9 for his career. They are pretty similar offensively in terms of volume shooting, 3-point ability, and general efficiency. If you are only looking at their offense and assuming they are similar defensively, then you'd have to determine if their figures this season are fully representative or not. If you go by career, AA is more efficient. If you go by this year only, Mayo is off the charts in efficiency and Afflalo is just really solid. Either one would be a no-brainer upgrade over Singler, who plays textbook basketball, but who can't seem to create much offense on an unassisted basis.
