I see it literally everywhere.

Mac has him beat in nearly every category, most of them by a big margin, and does it with perhaps the worst supporting cast in the league. By what metric is Wilson supposed to be better?
Edit: worse*, and yes, they both suck
Physical abilities. Wilson has a stronger arm.
The thinking is since Mac already has horrible decision making, mechanics, pocket presence, etc that it would be better to try developing a guy with all those things who at least has an NFL arm.
