The problem is that some pilots figure out pretty quick after a few duff landings that the design and build of the SEP Cessna and piper is so good that you can make a complete arse of the landing and they will for the most part square themselves up and roll out in a very forgiving manner, a visit to any GA field on a cross wind day will see all kinds of landings while still in the crab or with a whole heap of drift or too much speed with no penalty apart from stressed gear which can lead to a relaxing of focus. With the tail dragger the constant thought of the expense and humiliation of a ground loop tends to make you focus on the goal of doing the best you can every time.
