Returners haven't been as fun for the last six seasons. It isn't just because of the gunner builds getting better, it is because blocking on special teams is pretty much broken. You can have three pieces of hold block gear on a dot designed to hold blocks and it will look like the other dot is covered in Vaseline, even if that dot has no break block gear and is designed to be a hard hitter instead of a block breaker.
It used to be that you could score on special teams if you could break two-three blocks, but in the modern sim you need the other team to just lose containment (punt team converges on the punter and leave the outside wide open) or to break/fake 6+ dots. The investment in special teams used to garner results, such that two otherwise equal teams could be decided by a couple of special teams returns.
These days, the only players making stats are playing in Regional Competitive leagues against CPUs and scrubs:

Pretty much all of those stats were chewed up against inferior leagues and inferior teams, while very few stats came from teams of equal quality.
